This commit moves the providers for `NgZone`-based change detection to a
single provider function. This function is currently called by default
in all places where `NgZone` was provided
(`bootstrapApplication`, `bootstrapModule`, and `TestBed`).
When we want to make Angular applications zoneless by default, we
can make a public provider method that has to be used in order to enable
the zone change detection features. When this method is not called,
Angular would use `NoopNgZone` by default and not initialize any
subscriptions to the `NgZone` stability events.
Side note: There are actually two places that `NgZone` is provided for `TestBed`
(providers in `compileTestModule` and `BrowserTestingModule`). This
likely doesn't need to be in both locations.

- update `errors.ts` to annotate the error NG0403, so that the runtime can add a link to that guide when an error is thrown
- update `application_ref_spec.ts` to include the new link of the error
- update `errors.md` as a result of running `yarn bazel test packages/core/test`

This commit updates the logic related to the attribute and property binding rules for <iframe> elements. There is a set of <iframe> attributes that may affect the behavior of an iframe and this change enforces that these attributes are only applied as static attributes, making sure that they are taken into account while creating an <iframe>.
If Angular detects that some of the security-sensitive attributes are applied as an attribute or property binding, it throws an error message, which contains the name of an attribute that is causing the problem and the name of a Component where an iframe is located.
BREAKING CHANGE:
Existing iframe usages may have security-sensitive attributes applied as an attribute or property binding in a template or via host bindings in a directive. Such usages would require an update to ensure compliance with the new stricter rules around iframe bindings.

This reverts commit 2d08965b1a.
The reason for revert is that we've identified some issues with implementation. The issues will get addressed soon and the fix would be re-submitted.
PR Close#47959
This commit updates the logic related to the attribute order on iframes and makes the rules more strict. There is a set of iframe attributes that may affect the behavior of an iframe, this change enforces that these attributes are applied before an `src` or `srcdoc` attributes are applied to an iframe, so that they are taken into account.
If Angular detects that some of the attributes are set after the `src` or `srcdoc`, it throws an error message, which contains the name of ann attribute that is causing the problem and the name of a Component where an iframe is located. In most cases, it should be enough to change the order of attributes in a template to move the `src` or `srcdoc` ones to the very end.
BREAKING CHANGE:
Existing iframe usages may have `src` or `srcdoc` preceding other attributes. Such usages may need to be updated to ensure compliance with the new stricter rules around iframe bindings.

Currently if the `ENVIRONMENT_INITIALIZER` token is not configured with `multi: true` flag, the code fails while trying to iterate over the value. This commit checks whether the `ENVIRONMENT_INITIALIZER` token value type is an array and throws a helpful error message.

Previously, when instantiating a component, Angular would look in the DI
hierarchy for `RendererFactory2`. Any DI tree which rolls up through an
application injector (that is, one created with `BrowserModule`) should be
able to provide this interface. If not found, Angular would switch to the
experimental `Renderer3` mechanism. This switch was designed this way,
because it allowed for the creation of experimental applications where
`RendererFactory2` was not included in the bundle at all.
In this commit, instead of automatically falling back on `Renderer3`-style
rendering, an error is raised instead if `RendererFactory2` is missing from
the DI hierarchy.
PR Close#46605
the formatted error messages always include a period separator between the
provided error message and the find-more suffix, this is not always
desirable as it may add periods when they shoud not be, so improve the
formatting by checking and applying the period only if the provided message
doesn't end with a character which already represents a separator
additionally also improve the formatting by trimming the provided error
message
note that such trimming needs to be performed before the separator check
so that for example an error message like `"some error! "` doesn't produce
`"some error! ."` but it successfully produces "some error!"

This commit narrows down acceptable argument types of the
`importProvidersFrom` function. More specifically, it rejects
standalone components as a source of imports.
PR Close#45837
`importProvidersFrom` provides a bridge from the world of NgModule-based DI
configuration to the new, "standalone" world of direct providers and
environment injectors. Early user feedback suggested some confusion around
where this function was supposed to be used, particularly around importing
NgModule-based providers into standalone component `providers` arrays, which
is not the intended use. This confusion is exacerbated by the fact that due
to the unified `Provider` type, this kind of misconfiguration was happily
accepted by the type system.
This commit changes the return type of `importProvidersFrom` to wrap the
returned providers in an opaque type that prevents them from being used in
component provider contexts. This, together with stronger documentation
around the purpose and functionality of `importProvidersFrom`, should
address some of the above confusion.

This commit implements the `bootstrapApplication` function that allows bootstrapping an application and pass a standalone component as a root component.
PR Close#45674
This commit implements the `destroy` method on the `ApplicationRef` class. This feature is a preparation for the new logic to bootstrap (and teardown) standalone components (without going through the `NgModuleRef` destroy), which would return an instance of the `ApplicationRef` (the current bootstrap APIs return an instance of the `NgModuleRef`).

This commit refactors the `RuntimeError` class to support a short version of providing error messages:
```
throw new RuntimeError(
RuntimeErrorCode.INJECTOR_ALREADY_DESTROYED,
ngDevMode && 'Injector has already been destroyed.');
```
In prod mode, the second argument becomes `false` andn this commit extends the typings to support that.
This commit also contains a couple places were the `RuntimeError` class is used to demostrate the compact form.

This commit moves some logic to make the location of runtime error codes consistent across packages. Now all error codes are located in `packages/core/src/errors.ts` file.

This commit removes the View Engine runtime. Itself, this change is
relatively straightforward, but it represents the final step in a multi-year
journey. It's only possible due to the hard work of many current and former

Since `ErrorHandler#handleError()` expects an argument of type `any` it
should be able to handle values such as `null` and `undefined`.
Previously, it failed to handle these values, because it was trying to
access properties on them.
This commit fixes it by ensuring no properties are accessed on `null` or
`undefined` values.
NOTE: This is part of fully addressing #28106.

The main use case for the generated source maps is to give
errors a meaningful context in terms of the original source
that the user wrote.
Related changes that are included in this commit:
* renamed virtual folders used for jit:
* ng://<module type>/module.ngfactory.js
* ng://<module type>/<comp type>.ngfactory.js
* ng://<module type>/<comp type>.html (for inline templates)
* error logging:
* all errors that happen in templates are logged
from the place of the nearest element.
* instead of logging error messages and stacks separately,
we log the actual error. This is needed so that browsers apply
source maps to the stack correctly.
* error type and error is logged as one log entry.
Note that long-stack-trace zone has a bug that
disables source maps for stack traces,
see https://github.com/angular/zone.js/issues/661.
BREAKING CHANGE:
- DebugNode.source no more returns the source location of a node.
