In Angular, it used to be an accepted practice to use strings as dependency
injection tokens. E.g. {provide: 'test', useValue: 'provided'}. However,
the Ivy node injection system did not support this. The Ivy DI system
attempts to patch a Bloom bit index onto each type registered with it, and
this patch operation does not work for a string token.
This commit adds string token support to the bloom filter system by
reserving bit 0 for string tokens. This eliminates the need for each string
token to store its own Bloom bit, at the expense of slightly more expensive
lookups of string tokens.

BREAKING CHANGE:
The public API for `DebugNode` was accidentally too broad. This change removes
1. Public constructor. Since `DebugNode` is a way for Angular to communicate information
on to the developer there is no reason why the developer should ever need to
Instantiate the `DebugNode`
2. We are also removing `removeChild`, `addChild`, `insertBefore`, and `insertChildAfter`.
All of these methods are used by Angular to constructor the correct `DebugNode` tree.
There is no reason why the developer should ever be constructing a `DebugNode` tree
And these methods should have never been made public.
3. All properties have been change to `readonly` since `DebugNode` is used by Angular
to communicate to developer and there is no reason why these APIs should be writable.
While technically breaking change we don’t expect anyone to be effected by this change.

A recent commit (probably 2c7386c) has changed the import graph of the
DI types in core, and somehow results in the ngc compiler deciding to
re-export core DI types from application factories which tangentially
use inject(). This is not really surprising; ngc's import graph can be
very unstable.
However, this results in a re-export of InjectFlags surviving JS
compilation. InjectFlags was a const enum, akin to an interface in TS,
with no runtime repesentation. This causes a warning to be emitted by
Webpack when it sees the re-export of InjectFlags.
This commit avoids the issue by removing 'const' from the declaration
of InjectFlags, causing it to have a runtime value. This is a temporary
fix. The real fix will be for ngc to no longer write exports of const
enums.
Testing strategy: manually verified. Due to the problem only manifesting
when recompiling after a change and then running Webpack, there is no
existing framework via which this could be easily tested with an
integration test. Additionally, the potential for this issue is gone in
Ivy, so this solution is only temporarily needed.
Fixes#27251.

These paths are no longer needed / used.
I had to disable one jit mode spec because it fails now that we actually run it.
I root caused the jit test failure as missing forwardRef support. See FW-645.

Currently we store the `_appRef` when a `ViewRef` is attached, however we don't use it for anything. These changes use it to detach the view from the `ApplicationRef` when it is destroyed. These changes also fix that the `ComponentRef` doesn't remove its `ViewRef` on destroy.

When ngtsc compiles @angular/core, it rewrites core imports to the
r3_symbols.ts file that exposes all internal symbols under their
external name. When creating the FESM bundle, the r3_symbols.ts file
causes the external symbol names to be rewritten to their internal name.
Under ngcc compilations of FESM bundles, the indirection of
r3_symbols.ts is no longer in place such that the external names are
retained in the bundle. Previously, the external name `ɵdefineNgModule`
was explicitly declared internally to resolve this issue, but the
recently added `setClassMetadata` was not declared as such, causing
runtime errors.
Instead of relying on the r3_symbols.ts file to perform the rewrite of
the external modules to their internal variants, the translation is
moved into the `ImportManager` during the compilation itself. This
avoids the need for providing the external name manually.

Currently the `useJit` option from `TestBed.configureCompiler` isn't supported. These changes rework the existing test suites not to pass in `useJit` when running with Ivy.

This API is part of our public api surface and needs to be monitored by the public_api_guard.
I also had to go back and mark all of the exported functions with @publicApi jsdoc tag.
