Bjarki ef892743ec feat(compiler): support tagged template literals in code generator (#39122)
Add a TaggedTemplateExpr to represent tagged template literals in
Angular's syntax tree (more specifically Expression in output_ast.ts).
Also update classes that implement ExpressionVisitor to add support for
tagged template literals in different contexts, such as JIT compilation
and conversion to JS.

Partial support for tagged template literals had already been
implemented to support the $localize tag used by Angular's i18n
framework. Where applicable, this code was refactored to support
arbitrary tags, although completely replacing the i18n-specific support
for the $localize tag with the new generic support for tagged template
literals may not be completely trivial, and is left as future work.

cexbrayat 67c5fe06e6 docs: improve FormBuilder.group deprecation message (#39946)
This expands the deprecation message that started to pop up in v11.0.3
after the landing of commit e148382bd0,
that deprecated the `{[key: string]: any}` type for the options property of the `FormBuilder.group` method.

It turns out that having a custom validator declared as
`{ validators: (group: FormGroup) => ValidationErrors|null }` works in practice,
but is now inferred by TS as the deprecated version of `group`
(because `FormGroup` is a subclass of `AbstractControl` that `ValidatorFn` expects).
We considered the possibility of tweaking the forms API to accept such validators,
but it turns out to generate too many changes in the framework or possible breaking changes for Angular users.

We settled for a more explicit deprecation message, elaborated with the help of @petebacondarwin.
This will hopefully help developers to understand why the deprecation warning is showing up
when they think they are already using the non-deprecated overload.

ayazhafiz 3b700985f0 fix(language-service): do not treat file URIs as general URLs (#39917)
In the past, the legacy (VE-based) language service would use a
`UrlResolver` instance to resolve file paths, primarily for compiler
resources like external templates. The problem with this is that the
UrlResolver is designed to resolve URLs in general, and so for a path
like `/a/b/#c`, `#c` is treated as hash/fragment rather than as part
of the path, which can lead to unexpected path resolution (f.x.,
`resolve('a/b/#c/d.ts', './d.html')` would produce `'a/b/d.html'` rather
than the expected `'a/b/#c/d.html'`).

This commit resolves the issue by using Node's `path` module to resolve
file paths directly, which aligns more with how resources are resolved
in the Ivy compiler.

The testing story here is not great, and the API for validating a file
path could be a little bit prettier/robust. However, since the VE-based
language service is going into more of a "maintenance mode" now that
there is a clear path for the Ivy-based LS moving forward, I think it is
okay not to spend too much time here.

Alex Rickabaugh c7c5b2fc1e fix(compiler-cli): correct incremental behavior even with broken imports (#39923)
When the compiler is invoked via ngc or the Angular CLI, its APIs are used
under the assumption that Angular analysis/diagnostics are only requested if
the program has no TypeScript-level errors. A result of this assumption is
that the incremental engine has not needed to resolve changes via its
dependency graph when the program contained broken imports, since broken
imports are a TypeScript error.

The Angular Language Service for Ivy is using the compiler as a backend, and
exercising its incremental compilation APIs without enforcing this
assumption. As a result, the Language Service has run into issues where
broken imports cause incremental compilation to fail and produce incorrect
results.

This commit introduces a mechanism within the compiler to keep track of
files for which dependency analysis has failed, and to always treat such
files as potentially affected by future incremental steps. This is tested
via the Language Service infrastructure to ensure that the compiler is doing
the right thing in the case of invalid imports.

Alex Rickabaugh a6c8cc3215 test(compiler-cli): validate broken external template incrementality (#39923)
Previously, if a component had an external template with a hard error, the
compiler would "forget" the link between that component and its NgModule.
Additionally, the NgModule would be marked as being in error, because the
template issue would prevent the compiler from registering the component
class as a component, so from the NgModule it would look like a declaration
of a non-directive/pipe class. As a combined result, the next incremental
step could fix the template error, but would not refresh diagnostics for the
NgModule, leading to an incrementality issue.

The various facets of this problem were fixed in prior commits. This commit
adds a test verifying the above case works now as expected.

Alex Rickabaugh 0823622202 fix(compiler-cli): track poisoned scopes with a flag (#39923)
To avoid overwhelming a user with secondary diagnostics that derive from a
"root cause" error, the compiler has the notion of a "poisoned" NgModule.
An NgModule becomes poisoned when its declaration contains semantic errors:
declarations which are not components or pipes, imports which are not other
NgModules, etc. An NgModule also becomes poisoned if it imports or exports
another poisoned NgModule.

Previously, the compiler tracked this poisoned status as an alternate state
for each scope. Either a correct scope could be produced, or the entire
scope would be set to a sentinel error value. This meant that the compiler
would not track any information about a scope that was determined to be in
error.

This method presents several issues:

1. The compiler is unable to support the language service and return results
when a component or its module scope is poisoned.

This is fine for compilation, since diagnostics will be produced showing the
error(s), but the language service needs to still work for incorrect code.

2. `getComponentScopes()` does not return components with a poisoned scope,
which interferes with resource tracking of incremental builds.

If the component isn't included in that list, then the NgModule for it will
not have its dependencies properly tracked, and this can cause future
incremental build steps to produce incorrect results.

This commit changes the tracking of poisoned module scopes to use a flag on
the scope itself, rather than a sentinel value that replaces the scope. This
means that the scope itself will still be tracked, even if it contains
semantic errors. A test is added to the language service which verifies that
poisoned scopes can still be used in template type-checking.

Alex Rickabaugh 6d42954327 fix(compiler-cli): remove the concept of an errored trait (#39923)
Previously, if a trait's analysis step resulted in diagnostics, the trait
would be considered "errored" and no further operations, including register,
would be performed. Effectively, this meant that the compiler would pretend
the class in question was actually undecorated.

However, this behavior is problematic for several reasons:

1. It leads to inaccurate diagnostics being reported downstream.

For example, if a component is put into the error state, for example due to
a template error, the NgModule which declares the component would produce a
diagnostic claiming that the declaration is neither a directive nor a pipe.
This happened because the compiler wouldn't register() the component trait,
so the component would not be recorded as actually being a directive.

2. It can cause incorrect behavior on incremental builds.

This bug is more complex, but the general issue is that if the compiler
fails to associate a component and its module, then incremental builds will
not correctly re-analyze the module when the component's template changes.
Failing to register the component as such is one link in the larger chain of
issues that result in these kinds of issues.

3. It lumps together diagnostics produced during analysis and resolve steps.

This is not causing issues currently as the dependency graph ensures the
right classes are re-analyzed when needed, instead of showing stale
diagnostics. However, the dependency graph was not intended to serve this
role, and could potentially be optimized in ways that would break this
functionality.

This commit removes the concept of an "errored" trait entirely from the
trait system. Instead, analyzed and resolved traits have corresponding (and
separate) diagnostics, in addition to potentially `null` analysis results.
Analysis (but not resolution) diagnostics are carried forward during
incremental build operations. Compilation (emit) is only performed when
a trait reaches the resolved state with no diagnostics.

This change is functionally different than before as the `register` step is
now performed even in the presence of analysis errors, as long as analysis
results are also produced. This fixes problem 1 above, and is part of the
larger solution to problem 2.

This commit adds "find references" functionality to the Ivy integrated

1. Generate shims for all files to ensure we find references in shims
throughout the entire program
2. Determine if the position for the reference request is within a
template.
  * Yes, it is in a template: Find which node in the template AST the
  position refers to. Then find the position in the shim file for that
  template node. Pass the shim file and position in the shim file along
  to step 3.
  * No, the request for references was made outside a template: Forward
  the file and position to step 3.
3. (`getReferencesAtTypescriptPosition`): Call the native TypeScript LS
`getReferencesAtPosition`. For each reference that is in a shim file, map those
back to a template location, otherwise return it as-is.

Currently we convert objects to strings using `'' + value` which is quickest,
but it stringifies the value using its `valueOf`, rather than `toString`. These
changes switch to using `String(value)` which has identical performance
and calls the `toString` method as expected. Note that another option
was calling `toString` directly, but benchmarking showed it to be slower.

I've included the benchmark I used to verify the performance so we have it
for future reference and we can reuse it when making changes to `renderStringify`
in the future.

Also for reference, here are the results of the benchmark:

```

Andrew Scott 68d4a74411 fix(core): Ensure OnPush ancestors are marked dirty when events occur (#39833)
We currently only wrap the event listener in the function which ensures
ancestors are marked for check when the listener is placed on an element
that has a native method for listening to an event. We actually need to do
this wrapping in all cases so that events that are attached to non-rendered
template items (`ng-template` and `ng-container`) also mark ancestors for check
when they receive the event.

JoostK e75244ec00 feat(compiler-cli): support for partial compilation of components (#39707)
This commit implements partial compilation of components, together with
linking the partial declaration into its full AOT output.

This commit does not yet enable accurate source maps into external
templates. This requires additional work to account for escape sequences
which is non-trivial. Inline templates that were represented using a
string or template literal are transplated into the partial declaration
output, so their source maps should be accurate. Note, however, that
the accuracy of source maps is not currently verified in tests; this is
also left as future work.

The golden files of partial compilation output have been updated to
reflect the generated code for components. Please note that the current
output should not yet be considered stable.

JoostK e79ce386fc refactor(compiler-cli): allow visiting call expressions without an active linker (#39707)
The compilation result of components may have inserted template
functions into the constant pool, which would be inserted into the Babel
AST upon program exit. Babel will then proceed with visiting this newly
inserted subtree, but we have already cleaned up the linker instance
when exiting the program. Any call expressions within the template
functions would then fail to be processed, as a file linker would no
longer be available.

Since the inserted AST subtree is known not to contain yet more partial
declarations, it is safe to skip visiting call expressions when no
file linker is available.
