Angular allows for `<ng-content>` elements to include a selector which
filters which content-projected entries are inserted into the container
depending on whether or not the selector is matched.
With Ivy this feature has not fully worked due to the massive changes
that took place inside of Ivy's styling algorithm code (which is
responsible for assigning classes and styles to an element). This
fix ensures that content-projection can correctly identify which slot
an element should be placed into when class-based selectors are used.

Fixes the `DebugNode.references` returning a reference to the underlying comment node, rather than the `TemplateRef` that the reference is pointing to. The issue comes from the fact that `discoverLocalRefs` falls back directly to returning the native node, if the ref isn't pointing to a directive, rather than looking through the locals.
These changes resolve FW-870.

Prior to this change we performed prop and attr name validation at compile time, which failed in case a given prop/attr is an input to a Directive (thus should not be a subject to this check).

These tests validate the ability of the View Engine TestBed to consume
summary metadata, a mechanism which allows the TestBed to use
AOT-compiled components & directives in tests. It achieves this through
two operations which are independently obsolete in Ivy:
1. It injects CompileMetadataResolver, a View Engine specific compiler
internal class which extracts global analysis metadata from classes,
and uses it to construct summary metadata. This happens in a
beforeEach() block which calls createSummaries().
2. It uses TestBed.initTestEnvironment to pass summary metadata to the
TestBed itself. Any such metadata is ignored in Ivy.
Operation #1 makes it impossible to run these tests under Ivy, as the
CompileMetadataResolver is not available with an Ivy compiler.
Ivy itself does not rely on summary data, and the R3TestBed can depend
directly on AOT compiled components without it. Thus, the spirit of thes
tests is obsolete in an Ivy world.

PR Close#28003
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 ivy code generation was emmiting the projectionDef instruction in
a template where the <ng-content> tag was found. This code generation logic was
incorrect since the ivy runtime expects the projectionDef instruction to be present
in the main template only.
This PR ammends the code generation logic so that the projectionDef instruction is
emmitedin the main template only.

Prior to this commit, we had two different modes for change detection
execution for Ivy, depending on whether you called `bootstrap()` or
`renderComponent()`. In the former case, we would complete creation
mode for all components in the tree before beginning update mode for
any component. In the latter case, we would run creation mode and
update mode together for each component individually.
Maintaining code to support these two different execution orders was
unnecessarily complex, so this commit aligns the two bootstrapping
mechanisms to execute in the same order. Now creation mode always
runs for all components before update mode begins.
This change also simplifies our rendering logic so that we use
`LView` flags as the source of truth for rendering mode instead of
`rf` function arguments. This fixed some related bugs (e.g. calling
`ViewRef.detectChanges` synchronously after the view's creation
would create view nodes twice, view queries would execute twice, etc).

`NgModule` requires that `Component`s/`Directive`s/`Pipe`s are listed in
declarations, and that each `Component`s/`Directive`s/`Pipe` is declared
in exactly one `NgModule`. This change adds runtime checks to ensure
that these sementics are true at runtime.
There will need to be seperate set of checks for the AoT path of the
codebase to verify that same set of semantics hold. Due to current
design there does not seem to be an easy way to share the two checks
because JIT deal with references where as AoT deals with AST nodes.

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).

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.

Fixes#25018.
Instantiating a NgModuleRef from NgModuleFactory reuses the NgModuleDefinition if it is already present. However the NgModuleDefinition has a providers array which modified when tree shakable providers are instantiated. This corrupts the provider definitions the next time the same factory is used to create a new NgModuleRef - Two provider definitions can end up with the same index anf the injector could potentially return a completely wrong object for a provider token.
This scenario is more likely on the server where the same NgModuleFactory is reused across requests.
The fix clones the cached NgModuleDefinition so that any tree shakable providers added later do not affect the cached copy.

This commit bundles 3 important changes, with the goal of enabling tree-shaking
of services which are never injected. Ordinarily, this tree-shaking is prevented
by the existence of a hard dependency on the service by the module in which it
is declared.
Firstly, @Injectable() is modified to accept a 'scope' parameter, which points
to an @NgModule(). This reverses the dependency edge, permitting the module to
not depend on the service which it "provides".
Secondly, the runtime is modified to understand the new relationship created
above. When a module receives a request to inject a token, and cannot find that
token in its list of providers, it will then look at the token for a special
ngInjectableDef field which indicates which module the token is scoped to. If
that module happens to be in the injector, it will behave as if the token
itself was in the injector to begin with.
Thirdly, the compiler is modified to read the @Injectable() metadata and to
generate the special ngInjectableDef field as part of TS compilation, using the
PartialModules system.
Additionally, this commit adds several unit and integration tests of various
flavors to test this change.

BREAKING CHANGE:
Perviously, any provider that had an ngOnDestroy lifecycle hook would be created eagerly.
Now, only classes that are annotated with @Component, @Directive, @Pipe, @NgModule are eager. Providers only become eager if they are either directly or transitively injected into one of the above.
This also makes all `useValue` providers eager, which
should have no observable impact other than code size.
EXPECTED IMPACT:
Making providers eager was an incorrect behavior and never documented.
Also, providers that are used by a directive / pipe / ngModule stay eager.
So the impact should be rather small.
