When the `TargetBinder` was written, the only embedded-view-based nodes were templates, but now we have `{#if}`, `{#switch}` and `{#defer}` which have similar semantics. These changes rework the binder to account for the new nodes.

Adds extraction for accessors (getters/setters), rest params, and resolved type info for everything so far. This also refactors function extraction into a new class and splits tests for common class info and directive info into separate files.

Based on top of #51685
This expands on the extraction with information for directives, including inputs and outputs. As part of this change, I've refactored the extraction code related to class and to directives into their own extractor classes to more cleanly separate extraction logic based on type of statement.

This expands on the skeleton previously added to extract docs info for classes, including properties, methods, and method parameters. Type information and Angular-specific info (e.g. inputs) will come in future PRs.
PR Close#51733
This commit adds a barebones skeleton for extracting information to be used for extracting info that can be used for API reference generation. Subsequent PRs will expand on this with increasingly real extraction. I started with @alxhub's #51615 and very slightly polished to get to this minimal commit.
PR Close#51733
Adds support for passing in `@Component.styles` as a string. Also introduces a new `styleUrl` property on `@Component` for providing a single stylesheet. This is more convenient for the most common case where a component only has one stylesheet associated with it.

The code for detecting a Windows CI run from #51701 didn't work, because Bazel isolates the environment variables. These changes work around the issue by passing in a custom variable with the `--test_env` flag.

Currently internally Angular has some customized tsconfig files, because we don't align with the tsconfig of the rest of g3. These changes enable `noImplicitReturns` and `noPropertyAccessFromIndexSignature` to align better with the internal config.
PR Close#51728
Adds type checking for the contents of `if`, `switch` and `for` blocks.
**Note:** this is just an initial implementation to get some basic type checking working and to figure out the testing setup. We'll need special TCB structures for this syntax so that we can support type narrowing.

`NGMODULE_VE_DEPENDENCY_ON_IVY_LIB` was a ViewEngine related error. This commit removes the doc page but keeps a redirection for older versions still throwing this error.
PR Close#51588
Extends the compiler to add support for generating arrow functions in the output AST. This will be required for the `for` control flow block and we can potentially leverage it in other places to reduces the amount of generated code.
PR Close#51436
In local compilation mode it is not possible to use an imported string for component's template or styles as it cannot be resolved statically in compile time. There are some such use cases in g3 and potentially devs might incorporate such pattern. At the moment such pattern will cause the local compilation fail with generic error messages (e.g., so and so at position 1 is not a reference, etc). This change makes specific error messages with helpful hints for such cases. These new error messages can help devs to quickly resolve the issue as well as make it possible to identify existing issues in g3.

`tsickle` is not used in any code paths in 3P and we can remove
this complexity. The `tsickle` npm package has not been released
in a while and we are risking breakages with e.g. future TypeScript
versions.
Note that the `ng_module` rule was updated to not emit through
tsickle at all. The tsickle in 1P is done directly by `tsc_wrapped`
and our code path in `compiler-cli` is not needed at all.

This commit updates TestBed to wait for async component metadata resolution before compiling components.
Async metadata is added by the compiler in case a component uses defer blocks, which contain deferrable
symbols.
PR Close#51182
This commit updates compiler logic to generate the `setClassMetadataAsync` calls for components that used defer blocks. The `setClassMetadataAsync` function loads deferrable dependencies and invokes the `setClassMetadata` synchronously once everything is loaded. This change is needed to avoid eager references to deferrable symbols in component metadata in generated code.
PR Close#51182
A factory generator function called "i0.ɵɵgetComponentDepsFactory" is added to generate a factory function for component dependencies. This function will use the deps tracker to calculate the component's dependencies.
For standalone components the component imports (if exists) will be passed to this function. Alternatively this function can grab the imports directly from the decorate, but such extraaction needs some runtime logic which overlapps with what the trait compiler is doing. So better to pass the imports directly to this function at compile time.
PR Close#51089
In local mode the compiler combines the raw imports and exports and pass them to the injector definition as the imports field. It is not possible to filter out ng modules at compile time though, and it will be done in runtime.
Unit tests also added, and since that was the first time adding tests for local compilation some tweaks had to be made in order to disable diagnostics in local compilation mode in order for tests to run (such situation is also the case in real compilation where we ignore all teh diagnostics basically)

This commit updates the logic to drop regular imports when all symbols that it brings can be defer-loaded.
The change ensures that there is no mix of regular and dynamic imports present in a source file.
PR Close#51171
Stores the `deferred` block triggers as a map instead of an array, because triggers can't be duplicated and because having to search through an array will be inconvenient later on.
I've also added a `DeferredBlock.visitAll` method to deduplicate the logic from the various visitor implementations.
PR Close#51262
Updates the TemplateDefinitionBuilder class to generate the `defer` instruction for `{#defer}` blocks. Also generates dependency function that would be invoked at runtime (with dynamic imports inside).
PR Close#51162
This commit brings the logic to calculate teh set of dependencies for each defer block. For each dependency we also identify whether it can be defer-loaded or not.

This is a minor refactoring of the ComponentHandler class logic to extract helper function and types to the top level for simplicity and reuse across other functions of the class.
PR Close#51162
This commit adds a new class called `DeferredSymbolTracker` to keep track of all usages of a particular symbol within a source file and allow to detect whether a symbol can be defer loaded (i.e. if there are any references to a symbol).
PR Close#51162
This commit updates the output AST (and related visitors) to support dynamic imports. This functionality will be used later to generate the output for defer blocks.

Adds the logic to create `defer`-specific AST nodes from the generic HTML `BlockGroup` and `Block`. The logic for parsing the triggers will be in the next commit.

A minimal change to full compilation mode to work in local mode. Now compiler can compile components without ctor injections, though the compiled code missing the following items which will be added in subsequent commits:
* it does not produce `dependencies` for component definition.
* it fails if component has ctor injection
PR Close#50545
The compiler will only include analysis and compile phases in local mode. Also a new `compileLocal` method is added to the annotation handler for local compilation.
This commit makes no change to the full/partial compilation code paths.

An internal compiler option named `supportJitMode` is now available for use by the Angular CLI.
This option currently controls the emit of NgModule selector scope information. This emitted
information is only needed in AOT mode when an application also uses JIT. However, AOT mode
combined with JIT mode is not currently supported nor will work in the Angular CLI. With
the Angular CLI, JIT mode is only supported if the entire application is built in JIT mode.
Without this option, the CLI needs to manually perform a code transform to remove the information
and also replicate TypeScript's import eliding. This is can be a complicated operation and must
be continually kept up to date with any changes to both the Angular compiler and TypeScript.
The introduction of this new option alleviates these concerns while also removing several build
time actions that would otherwise need to be performed on every application build.
PR Close#51007
The new interface is discrete-unioned with the existing interface to cover the cases for local and global (i.e., full and partial) compilation modes.
This change of interface required some adjustmeents cross repo which explains the changes made to other files.

All attempts related to obtaining R3Reference for bootstrap, imports, exports and declarations are cut in local compilation mode.
This will allow the analysis to pass without any error diagnostics, but the result is a quite empty meta info. Next commits will add data to the meta so that the NgModule can be compiled more accurately.
PR Close#50577
An internal compiler option named `supportTestBed` is now available for use by the
Angular CLI. This option currently controls the extraction and emit of Angular class
metadata. This emitted information is only needed in AOT mode when using certain
TestBed APIs. However, AOT mode is currently not available for unit testing within
the Angular CLI. As a result, the metadata is not used within CLI generation applications
and in particular production applications. Without this option, the CLI needs to
manually perform a code transform to remove the metadata and also replicate TypeScript's
import eliding. This is can be a complicated operation and must be continually kept
up to date with any changes to both the Angular compiler and TypeScript. The introduction
of this new option alleviates these concerns.

If the compiler CLI is running through closure compiler, the trait
decorator handlers are converted from classes to functions as ES5
is picked as default output target for the bundled version.
The problem is that currently all trait handlers end up having the
same `name`. i.e. an empty string, and therefore adopting previous
traits from a previous build iteration result in the incorrect handler
being used for e.g. registrering, compiling etc- causing
ambiguous/confusing errors down the line in other parts.
We can look into changing the output target in the future, but even
then we are safer using an actual literal due to property renaming.
```$$closure$$NgModuleDecoratorHandler = function() {}`.
It is is questionable if we should just simply NOT run the compiler
through JSCompiler.
