This commit uses the NgModuleRouteAnalyzer introduced previously to
implement listLazyRoutes() for NgtscProgram. Currently this implementation
is limited to listing routes globally and cannot list routes for a given lazy
module. Testing seems to indicate that the CLI uses the global form, but this
should be verified.

`ngtsc` currently fails building a flat module out file on Windows because it generates an invalid flat module TypeScript source file. e.g:
```ts
5 export * from './C:\Users\Paul\Desktop\test\src\export';
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```
This is because `path.posix.relative` does not properly with non-posix paths, and only expects posix paths in order to work.

This code was throwing if the `deps` array of a provider has several elements, but at the next line it resolves them... With this check `ngtsc` couldn’t compile `ng-bootstrap` for example.

This update aligns Ivy behavior with ViewEngine related to empty bindings (for example <div [someProp]></div>): empty bindings are ignored.

ngtsc has a hack to add @nocollapse jsdoc annotations to generated static
fields. This hack is currently broken (likely due to a TypeScript change
in the way writeFile() works).
This commit fixes the hack and introduces an ngtsc_spec test to ensure it
does not regress again.

Prior to this change Component decorator was resolving `encapsulation` value a bit incorrectly, which resulted in `encapsulation: NaN` in compiled code. Now we resolve the value as Enum memeber and throw if it's not the case. As a part of this update, the `changeDetection` field handling is also added, the resolution logic is the same as the one used for `encapsulation` field.

Generated factory shims can import from @angular/core. However, we have
special logic in place to rewrite self-imports when generating code for
@angular/core.
This commit leverages the new standalone ImportRewriter interface to
properly rewrite imports in generated factory shims. Before this fix,
a generated factory file for core would look like:
```typescript
import * as i0 from './r3_symbols';
export var ApplicationModuleNgFactory = new ɵNgModuleFactory(...);
```
This is invalid, as ɵNgModuleFactory is just NgModuleFactory when imported
via r3_symbols.

This commit adds sanitization for `elementProperty` and `elementAttribute` instructions used in `hostBindings` function, similar to what we already have in the `template` function. Main difference is the fact that for some attributes (like "href" and "src") we can't define which SecurityContext they belong to (URL vs RESOURCE_URL) in Compiler, since information in Directive selector may not be enough to calculate it. In order to resolve the problem, Compiler injects slightly different sanitization function which detects proper Security Context at runtime.

Previously, ngtsc would assume that a given directive/pipe being imported
from an external package was importable using the same name by which it
was declared. This isn't always true; sometimes a package will export a
directive under a different name. For example, Angular frequently prefixes
directive names with the 'ɵ' character to indicate that they're part of
the package's private API, and not for public consumption.
This commit introduces the TsReferenceResolver class which, given a
declaration to import and a module name to import it from, can determine
the exported name of the declared class within the module. This allows
ngtsc to pick the correct name by which to import the class instead of
making assumptions about how it was exported.
This resolver is used to select a correct symbol name when creating an
AbsoluteReference.

This commit adds tracking of modules, directives, and pipes which are made
visible to consumers through NgModules exported from the package entrypoint.
ngtsc will now produce a diagnostic if such classes are not themselves
exported via the entrypoint (as this is a requirement for downstream
consumers to use them with Ivy).
To accomplish this, a graph of references is created and populated via the
ReferencesRegistry. Symbols exported via the package entrypoint are compared
against the graph to determine if any publicly visible symbols are not
properly exported. Diagnostics are produced for each one which also show the
path by which they become visible.
This commit also introduces a diagnostic (instead of a hard compiler crash)
if an entrypoint file cannot be correctly determined.

This update introduces support for global object (window, document, body) listeners, that can be defined via host listeners on Components and Directives.

Normally functions that return `ModuleWithProvider` objects should parameterize
the return type to include the type of `NgModule` that is being returned. For
example `forRoot(): ModuleWithProviders<RouterModule>`.
But in some cases, especially those generated by nccc, these functions to not
explicitly declare `ModuleWithProviders` as their return type. Instead they
return a "intersection" type, one of whose members is a type literal that
declares the `NgModule` type returned. For example:
`forRoot(): CustomType&{ngModule:RouterModule}`.
This commit changes the `NgModuleDecoratorHandler` so that it can extract
the `NgModule` type from either kind of declaration.
PR Close#27326
With ngcc's ability to fixup pre-Ivy ModuleWithProviders such that they
include a reference to the NgModule type, the type may become a qualified
name:
```
import {ModuleWithProviders} from '@angular/core';
import * as ngcc0 from './module';
export declare provide(): ModuleWithProviders<ngcc0.Module>;
```
ngtsc now takes this situation into account when reflecting a
ModuleWithProvider's type argument.

Closure Compiler doesn't allow non-goo.getMsg const names to start with `MSG_`, so we should use different prefix for const that references a result of the `i18nPostprocess` fn invocation. With this update we also append file-based prefix to i18n constants (via $$ postfix) to ensure the names are unique across codebase of a project (otherwise it might lead to errors while compiling a project with Closure Compiler).
PR Close#27468
Previously in Ivy, host bindings did not work if they shared a public name
with an Input because they used the `elementProperty` instruction as is.
This instruction was originally built for inside component templates, so it
would either set a directive input OR a native property. This is the
correct behavior for inside a template, but for host bindings, we always
want the native properties to be set regardless of the presence of an Input.
This change adds an extra argument to `elementProperty` so we can tell it to
ignore directive inputs and only set native properties (if it is in the
context of a host binding).

Analogously to directives, the `ngInjectableDef` field in .d.ts files is
annotated with the type of service that it represents. If the service
contains required generic type arguments, these must be included in
the .d.ts file.

A previous fix to ngtsc opened the door for duplicate directives in
the 'directives' array of a component. This would happen if the directive
was declared in a module which was imported more than once within the
component's module.
This commit adds deduplication when the component's scope is materialized,
so declarations which arrive via more than one module import are coalesced.

The method `ts.CompilerHost.directoryExists` is optional, and was not
previously handled by our ts.CompilerHost wrapper for factory and
summary shims (GeneratedShimsHostWrapper).
TypeScript checks for the existence of this method and silently ignores
things like typeRoots if it's not found. This commit adds proper handling
of directoryExists() to the shim.
A test is also added which verifies typeRoots behavior works when shims
are enabled.

Previously ngtsc assumed resource files (templateUrl, styleUrls) would be
physically present in the file system relative to the .ts file which
referenced them. However, ngc previously resolved such references in the
context of ts.CompilerOptions.rootDirs. Material depends on this
functionality in its build.
This commit introduces resolution of resources by leveraging the TypeScript
module resolver, ts.resolveModuleName(). This resolver is used in a way
which will never succeed, but on failure will return a list of locations
checked. This list is then filtered to obtain the correct potential
locations of the resource.

This commit adds support for resolution of styleUrls to ngtsc. Previously
this field was never read, and so components with styleUrls would appear
unstyled after compilation.

Previously the concept of multiple directives with the same selector was
not supported by ngtsc. This is due to the treatment of directives for a
component as a Map from selector to the directive, which is an erroneous
representation.
Now the directives for a component are stored as an array which supports
multiple directives with the same selector.
Testing strategy: a new ngtsc_spec test asserts that multiple directives
with the same selector are matched on an element.

This commit causes a call to setClassMetadata() to be emitted for every
type being compiled by ngtsc (every Angular type). With this metadata,
the TestBed should be able to recompile these classes when overriding
decorator information.
Testing strategy: Tests in the previous commit for
generateSetClassMetadataCall() verify that the metadata as generated is
correct. This commit enables the generation for each DecoratorHandler,
and a test is added to ngtsc_spec to verify all decorated types have
metadata generated for them.

This commit adds generation of .ngsummary.js shims alongside .ngfactory.js
shims when generated files are enabled.
Generated .ngsummary shims contain a single, null export for every exported
class with decorators that exists in the original source files. Ivy code
does not depend on summaries, so these exist only as a placeholder to allow
them to be imported and their values passed to old APIs. This preserves
backwards compatibility.
Testing strategy: this commit adds a compiler test to verify the correct
shape and contents of the generated .ngsummary.js files.

This commit gets ready for the introduction of ngtsc template
type-checking tests by refactoring test environment setup into a
custom helper. This helper will simplify the authoring of future
ngtsc tests.
Ngtsc tests previously returned a numeric error code (a la ngtsc's CLI
interface) if any TypeScript errors occurred. The helper has the
ability to run ngtsc and return the actual array of ts.Diagnostics, which
greatly increases the ability to write clean tests.

Previously in Ivy, metadata for directives/components/modules/etc was
carried in .d.ts files inside type information encoded on the
DirectiveDef, ComponentDef, NgModuleDef, etc types of Ivy definition
fields. This works well, but has the side effect of complicating Ivy's
runtime code as these extra generic type parameters had to be specified
as <any> throughout the codebase. *DefInternal types were introduced
previously to mitigate this issue, but that's the wrong way to solve
the problem.
This commit returns *Def types to their original form, with no metadata
attached. Instead, new *DefWithMeta types are introduced that alias the
plain definition types and add extra generic parameters. This way the
only code that needs to deal with the extra metadata parameters is the
compiler code that reads and writes them - the existence of this metadata
is transparent to the runtime, as it should be.

This fixes a bug in ngtsc where each @Directive was compiled using a

working properly.
