In View Engine, developers can pass bootstrap and entry components
as nested arrays. e.g.
```ts
export const MyOtherEntryComponents = [A, B, C]
@NgModule({
entryComponents: [MyComp, MyOtherEntryComponents]
})
```
Currently using nested arrays for these properties causes
unexpected errors to be reported in Ivy since the semantic
NgModule checks aren't properly recursing into the nested
entry/bootstrap components. This issue has been unveiled by
enabling the strict function parameter checks.
PR Close#30993
Currently the `ɵɵdefineComponent` method has incorrect type
definitions the `directives` and `pipes` metadata property.
The incorrect types allow developers to pass in already instantiated
`DirectiveDef` or `ComponentDef` objects. This can cause unexpected
failures because the definition internally only expects `Type` objects
and now incorrectly tries to read the `ngDirectiveDef` or `ngComponentDef`
of existing definitions.
This issue has been unveiled by enabling the strict function parameter
types flag, where the directive definitions are determined from each array
element in the `directives` or `pipes` property (which can throw).

The support for decorators that were imported via a namespace,
e.g. `import * as core from `@angular/core` was implemented
piecemeal. This meant that it was easy to miss situations where
a decorator identifier needed to be handled as a namepsaced
import rather than a direct import.
One such issue was that UMD processing of decorators was not
correct: the namespace was being omitted from references to
decorators.
Now the types have been modified to make it clear that a
`Decorator.identifier` could hold a namespaced identifier,
and the corresponding code that uses these types has been

Fixes Ivy matching directives against attribute bindings (e.g. `[attr.some-directive]="foo"`). Works by excluding attribute bindings from the attributes array during compilation. This has the added benefit of generating less code.
**Note:** My initial approach to implementing this was to have a different marker for attribute bindings so that they can be ignored when matching directives, however as I was implementing it I realized that the attributes in that array were only used for directive matching (as far as I could tell). I decided to drop the attribute bindings completely, because it results in less generated code.

Currently we reuse the same instruction both for regular property bindings and property bindings on the `host`. The only difference between the two is that when it's on the host we shouldn't support inputs. We have an optional parameter called `nativeOnly` which is used to differentiate the two, however since `nativeOnly` is preceeded by another optional parameter (`sanitizer`), we have to generate two extra parameters for each host property bindings every time (e.g. `property('someProp', 'someValue', null, true)`).
These changes add a new instruction called `hostProperty` which avoids the need for the two parameters by removing `nativeOnly` which is always set and it allows us to omit `sanitizer` when it isn't being used.
These changes also remove the `nativeOnly` parameter from the `updateSyntheticHostBinding` instruction, because it's only generated for host elements which means that we can assume that its value will always be `true`.

There are two places in the ngcc processing where it needs to load the
content of a file given by a general path:
* when determining the format of an entry-point.
To do this ngcc uses the value of the relevant property in package.json.
But in the case of `main` it must parse the contents of the entry-point
file to decide whether the format is UMD or CommonJS.
* when parsing the source files for dependencies to determine the order in
which compilation must occur. The relative imports in each file are parsed
and followed recursively, looking for external imports.
Previously, we naively assumed that the path would match the file name exactly.
But actually we must consider the standard module resolution conventions.
E.g. the extension (.js) may be missing, or the path may refer to a directory
containing an index.js file.
This commit fixes both places.
This commit now requires the `DependencyHost` instances to check
the existence of more files than before (at worst all the different possible
post-fixes). This should not create a significant performance reduction for
ngcc. Since the results of the checks will be cached, and similar work is
done inside the TS compiler, so what we lose in doing it here, is saved later
in the processing. The main performance loss would be where there are lots
of files that need to be parsed for dependencies that do not end up being
processed by TS. But compared to the main ngcc processing this dependency
parsing is a small proportion of the work done and so should not impact
much on the overall performance of ngcc.

When profiling ngcc it is notable that a large amount of time
is spent dealing with an exception that is thrown (and handled
internally by fs) when checking the existence of a file.
We check file existence a lot in both finding entry-points
and when TS is compiling code. This commit adds a simple
cached `FileSystem`, which wraps a real `FileSystem` delegate.
This will reduce the number of calls through to `fs.exists()` and
`fs.readFile()` on the delegate.
Initial benchmarks indicate that the cache is miss to hit ratio
for `exists()` is about 2:1, which means that we save about 1/3
of the calls to `fs.existsSync()`.
Note that this implements a "non-expiring" cache, so it is not suitable
for a long lived `FileSystem`, where files may be modified externally.
The cache will be updated if a file is changed or moved via
calls to `FileSystem` methods but it will not be aware of changes
to the files system from outside the `FileSystem` service.
For ngcc we must create a new `FileSystem` service
for each run of `mainNgcc` and ensure that all file operations
(including TS compilation) use the `FileSystem` service.
This ensures that it is very unlikely that a file will change
externally during `mainNgcc` processing.

This breaks down if the last node that was rendered was under the SVG or MathML namespace and we create a component through `ViewContainerRef.create`, because the next template function hasn't run yet and it hasn't had the chance to update the namespace. The result is that the root node of the new component will retain the wrong namespace and may not end up rendering at all (e.g. if we're trying to show a `div` inside the SVG namespace).

The Angular runtime frequently calls into user code (for example, when
writing to a property binding). Since user code can throw errors, calls to
it are frequently wrapped in a try-finally block. In Ivy, the following
pattern is common:
```typescript
enterView();
try {
callUserCode();
} finally {
leaveView();
}
```
This has a significant problem, however: `leaveView` has a side effect: it
calls any pending lifecycle hooks that might've been scheduled during the
current round of change detection. Generally it's a bad idea to run
lifecycle hooks after the application has crashed. The application is in an
inconsistent state - directives may not be instantiated fully, queries may
not be resolved, bindings may not have been applied, etc. Invariants that
the app code relies upon may not hold. Further crashes or broken behavior
are likely.
Frequently, lifecycle hooks are used to make assertions about these
invariants. When these assertions fail, they will throw and "swallow" the
original error, making debugging of the problem much more difficult.
This commit modifies `leaveView` to understand whether the application is
currently crashing, via a parameter `safeToRunHooks`. This parameter is set
by modifying the above pattern:
```typescript
enterView();
let safeToRunHooks = false;
try {
callUserCode();
safeToRunHooks = true;
} finally {
leaveView(..., safeToRunHooks);
}
```
If `callUserCode` crashes, then `safeToRunHooks` will never be set to `true`
and `leaveView` won't call any further user code. The original error will
then propagate back up the stack and be reported correctly. A test is added
to verify this behavior.

occasionally libraries publish their typings in the same directory
structure as the compiled JS files, i.e. adjacent to each other.

To improve cross platform support, all file access (and path manipulation)
is now done through a well known interface (`FileSystem`).
For testing a number of `MockFileSystem` implementations are provided.
These provide an in-memory file-system which emulates operating systems
like OS/X, Unix and Windows.
The current file system is always available via the static method,
`FileSystem.getFileSystem()`. This is also used by a number of static
methods on `AbsoluteFsPath` and `PathSegment`, to avoid having to pass
`FileSystem` objects around all the time. The result of this is that one
must be careful to ensure that the file-system has been initialized before
using any of these static methods. To prevent this happening accidentally
the current file system always starts out as an instance of `InvalidFileSystem`,
which will throw an error if any of its methods are called.
You can set the current file-system by calling `FileSystem.setFileSystem()`.
During testing you can call the helper function `initMockFileSystem(os)`
which takes a string name of the OS to emulate, and will also monkey-patch
aspects of the TypeScript library to ensure that TS is also using the
current file-system.
Finally there is the `NgtscCompilerHost` to be used for any TypeScript
compilation, which uses a given file-system.
All tests that interact with the file-system should be tested against each
of the mock file-systems. A series of helpers have been provided to support
such tests:
* `runInEachFileSystem()` - wrap your tests in this helper to run all the
wrapped tests in each of the mock file-systems.
* `addTestFilesToFileSystem()` - use this to add files and their contents
to the mock file system for testing.
* `loadTestFilesFromDisk()` - use this to load a mirror image of files on
disk into the in-memory mock file-system.
* `loadFakeCore()` - use this to load a fake version of `@angular/core`
into the mock file-system.
All ngcc and ngtsc source and tests now use this virtual file-system setup.

No longer uses docker in order to pull down the toolchain configs
for remote build execution. We don't need to make docker a prerequisite
for working on the Angular repository since we can leverage the checked-in
toolchain configurations from the `@bazel-toolchains` repository.

Prior to this commit, the logic to extract query information from class fields used an instance of regular Error class to throw an error. As a result, some useful information (like reference to a specific field) was missing. Replacing Error class with FatalDiagnosticError one makes the error more verbose that should simplify debugging.

ctx.actions.declare_file now used in @angular/bazel ng_module rule as ctx.new_file is now deprecated. Fixes error:
```
File "ng_module.bzl", line 272, in _expected_outs
ctx.new_file(ctx.genfiles_dir, (ctx.label.name ..."))
Use ctx.actions.declare_file instead of ctx.new_file.
Use --incompatible_new_actions_api=false to temporarily disable this check.
```
This can be worked around with incompatible_new_actions_api flag but may as well fix it proper so downstream doesn't require this flag due to this code.
Also, depset() is no longer iterable by default without a flag. This required fixing in a few spots in @angular/bazel.

In ViewEngine injecting a Renderer2 returns a renderer that is specific to the particular component, however in Ivy we inject the renderer for the parent view instead. This causes it to set incorrect `ngcontent` attributes when creating elements through the renderer.
The issue comes from the fact that the `Renderer2` is created according to the current `LView`, but because DI happens before we've entered the `LView` of the component that's injecting the renderer, we end up with one that's one level up. We work around the issue by finding the `LView` that corresponds to the `previousOrParentTNode` inside of the parent view and associating the `Renderer2` with it.
This PR resolves FW-1382.

Previously, multiple ViewContainerRef instances (obtained by injecting
ViewContainerRef multiple times) each had private state that could be out of
sync with actual LContainer, if views were inserted/removed/queried across
the different instances. In particular each instance had its own array which
tracked ViewRefs inserted via that instance.
This commit moves the ViewRefs array onto the LContainer itself, so that it
can be shared across multiple ViewContainerRef instances. A test is added
that verifies ViewContainerRefs now provide a consistent view of the
container.

Optimizations to skip compiling source files that had not changed
did not account for the case where only a resource file changes,
such as an external template or style file.
Now we track such dependencies and trigger a recompilation
if any of the previously tracked resources have changed.
This will require a change on the CLI side to provide the list of
resource files that changed to trigger the current compilation by
implementing `CompilerHost.getModifiedResourceFiles()`.

Adds two new helper functions that can be used when unit testing Angular services
that depend upon upgraded AngularJS services, or vice versa.
The functions return a module (AngularJS or NgModule) that is configured to wire up
the Angular and AngularJS injectors without the need to actually bootstrap a full
hybrid application.
This makes it simpler and faster to unit test services.
