This works for the code actions and completion. When the ls wants to complete
all importable angular metadata in the template, the ls will invoke the function
`ls.getCompletionsAtPosition` and filter the item about the angular. When the
developer selects an item, the ls will get the module specifier from the code action
return by the `ls.getCompletionEntryDetails`.

This commit migrates the remaining pieces of `compiler-cli` to
`ts_project`. This involves a few more things during migration:
- the `ng_module` ngc_wrapped rule broke as part of this change, so we
switched it to `ts_project` too. This logic is soon gone anyway.
- we needed an extra pnpm "package.json" for the linker babel test. This test is
loading from the real compiler-cli npm package. Babel needs a real
node module for this, so this solution seems reasonable. It may be
worth exploring in the future to move this test into an integration
test though.
- the older integrationtest in compiler-cli is removed as the coverage
is much better with the compliance test suite and this test.

When defer blocks have a reference-based trigger without a parameter, we infer it from the placeholder block. This requires some validations like ensuring that there's only one element in the placeholder. The validations are currently implemented at the parser level which can affect tools like linters that need to pass `preserveWhitespaces: true` in order to get accurate source mappings.
These changes move the validations into the template type checker so that they still get flagged, but much later in the process. Moving them over involves a bit more work, because the template type checker also sets `preserveWhitespaces: true`.

Replaces the `propertyInterpolateX` instructions with calls to `property` and the `interpolate` helper. This allows us to drop the dedicated interpolation instructions and simplify the runtime for future work.
PR Close#61639
Replaces the `classMapInterpolateX` instructions with `classMap` plus a call to `interpolate` in order to simplify the runtime. The only difference between `classMapInterpolateX` and `classMap` was that the former passes `keyValueArraySet` into `checkStylingMap` while the latter passes `classKeyValueArraySet`. This doesn't appear to matter, because the interpolation instructions always have a string value which means that the function is never called.

Currently we construct the HMR replacement URL inline by calling into the native `URL` constructor. This can cause conflicts with user code that defines a symbol called `URL`.
These changes resolve the issue by moving the URL construction into a separate function. This has a secondary benefit of making the generated code easier to follow and allowing us to update the URL without changing the compiled code.

In declaration-only emission mode, the compiler extracts the type
declarations (.d.ts) files without full type-checking, which is possible
with sufficient type annotations on exports that can be ensured by the
`isolatedDeclarations` TS compiler option.
This allows us to decouple type declaration emission from the actual
full compilation doing the type-checking, thereby removing the
edge between dependent TS files in the build action graph. In other
words, the compilation of a TS file no longer indirectly depends on the
compilation of all the TS files it imports through its dependency on
their type declarations, because the type declarations themselves no
longer depend on the compilation of their associated TS file.
Without the coupling between type declaration emission and compilation,
compilation time of a TS project is no longer bound dependent on the
depth of the TS dependency tree as we can now build the entire project
with just two entirely parallel phases: 1) emit the type declarations of
all TS files in parallel and 2) compile all TS files in parallel.
Since the Angular compiler adds static metadata fields to components,
directives, modules, pipes and services based on their respective class
annotations, it needs to actively partake in the type declaration
emission in order to provide the types for these static fields in the
declaration.
In this change, we add experimental support for a declaration-only
emission mode based on the local compilation mode, which already
operates without type-checking and access to external type information,
i.e. the same environment as is required for declaration-only emisssion.
Apart from the same restrictions applied in local compilation mode,
there are a few more restrictions imposed on code being compatible with
this initial and experimental implementation:
* No support for `@NgModule`s using external references.
* No support for `hostDirectives` in `@Component`s and `@Directive`s
using external references
* No support for `@Input` annotations with `transform`.

The compiler wasn't handling `@let` declarations placed inside i18n blocks. The problem is that `assignI18nSlotDependencies` phase assigns the `target` of i18n ops much earlier than the `@let` optimization. If the `@let` ends up getting optimized because it isn't used in any child views, the pointer in the i18n instruction becomes invalid. This hadn't surfaced so far, because we didn't optimize `declareLet` ops, however once we do, we start hitting assertions that the optimized `declareLet` isn't used anywhere.
These changes resolve the issue by moving the i18n phases after the `@let` optimization.

We have some code that avoids `storeLet` calls for declarations only used in the same view, however we didn't previously remove the corresponding `declareLet` calls, because of the following case:
```
@let foo = something$ | async; <!-- First in the template -->
{{foo}}
```
Here we need a `TNode` (created by `declareLet`) in order for DI to work correctly. Since this is only required when using pipes, we can optimize away expressions that do not have pipes.

By default, the compiler-cli uses the relative import strategy when
there is no `rootDir` or `rootDirs`. This is expected as everything is
assumed to be somehow reachable through relative imports.
With `rootDirs` that allow for a "virtual file system"-like environment,
the compiler is not necessarily able to always construct proper relative
imports. The compiler includes the `LogicalProjectStrategy` for this
reason. This strategy is able to respect `rootDirs` to construct
relative paths when possible.
This logic currently accidentally triggers when there is a `rootDir`
set. This option is not to be confused with the virtual directory
option called `rootDirs`. The compiler currently confuses this and
accidentally enters this mode when there is just a `rootDir`— breaking
in monorepos that imports can point outside the `rootDir` to e.g. other
compilation unit's `.d.ts` (which is valid; just not `.ts` sources can
live outside the root dir).
This is necessary for our Bazel toolchain migration.

The `TemplateLiteralElementExpr` has some logic where it tries to estimate the `rawText` if one isn't provided by looking at the node's source span. The problem with this approach is that we have some long-standing issues with our expression AST parser (see https://github.com/angular/angular/pull/60267#discussion_r1986402524) where it might not produce accurate spans if escape sequences are involved. This in turn can lead to unrecoverable errors, because TypeScript will throw an error if the raw string doesn't match the cooked one when constructing a TypeScript AST node.
These changes remove the logic that depends on the source span and relies purely on the secondary fallback that inserts escaped characters manually.
It's also worth noting that the `rawText` doesn't seem to matter much at this point, because the main usage of it is when downlevelling template literals to ES5 which we no longer support.
