Prior to this change default selector for Components was not applied in case selector is missing or defined as an empty string. This update aligns this behavior between Ivy and VE: now default selector is used for Components when it's needed. Directives with empty selector are not allowed and trigger a compile-time error in both Ivy and VE.

This commit adds support for the `static: true` flag in
`ViewChild` queries. Prior to this commit, all `ViewChild`
queries were resolved after change detection ran. This is
a problem for backwards compatibility because View Engine
also supported "static" queries which would resolve before
change detection.
Now if users add a `static: true` option, the query will be
resolved in creation mode (before change detection runs).
For example:
```ts
@ViewChild(TemplateRef, {static: true}) template !: TemplateRef;
```
This feature will come in handy for components that need
to create components dynamically.

This commit turns off an unknown binding test that is specific
to the View Engine implementation. In Ivy, we do property validation
at runtime for jit, so this test does not apply.
PR Close#28740
Accounts for schemas in when validating properties in Ivy.
This PR resolves FW-819.
A couple of notes:
* I had to rework the test slightly, in order to have it fail when we expect it to. The one in master is passing since Ivy's validation runs during the update phase, rather than creation.
* I had to deviate from the design in FW-819 and not add an `enableSchema` instruction, because the schema is part of the `NgModule` scope, however the scope is only assigned to a component once all of the module's declarations have been resolved and some of them can be async. Instead, I opted to have the `schemas` on the component definition.

Due to the fact that host nodes no longer match in ContentChild queries in Ivy, we disable test that was enabled previously in other commit.
PR Close#28660
Prior to this change in Ivy we had strict check that disabled non-unique #localRefs usage within a given template. While this limitation was technically present in View Engine, in many cases View Engine neglected this restriction and as a result, some apps relied on a fact that multiple non-unique #localRefs can be defined and utilized to query elements via @ViewChild(ren) and @ContentChild(ren). In order to provide better compatibility with View Engine, this commit removes existing restriction.
As a part of this commit, are few tests were added to verify VE and Ivy compatibility in most common use-cases where multiple non-unique #localRefs were used.

This commit adds a devMode-only check which will throw if a user
attempts to bind a property that does not match a directive
input or a known HTML property.
Example:
```
<div [unknownProp]="someValue"></div>
```
The above will throw because "unknownProp" is not a known
property of HTMLDivElement.
This check is similar to the check executed in View Engine during
template parsing, but occurs at runtime instead of compile-time.
Note: This change uncovered an existing bug with host binding
inheritance, so some Material tests had to be turned off. They
will be fixed in an upcoming PR.

Currently, DOM node removal called `removeChild` on the saved parent
node when destroying a component. However, this will fail if the
component has been manually moved in the DOM. This change makes the
removal always use the node's real `parentNode` and ignore the provided
`parent`.
PR Close#28455
Ivy allows Components to extend Directives (but not the other way around) and as a result we may have Component and Directive annotations present at the same time. The logic that resolves annotations to pick the necessary one didn't take this into account and as a result Components were recognized as Directives (and vice versa) in case of inheritance. This change updates the resolution logic by picking known annotation that is the nearest one (in inheritance tree) and compares it with expected type. That should help avoid mis-classification of Components/Directives during resolution.

In Ivy, we support a new manual mode that allows for stricter control
over change detection in OnPush components. Specifically, in this mode,
events do not automatically mark OnPush views as dirty. Only changed
inputs and manual calls to `markDirty()` actually mark a view dirty.
However, this mode cannot be the default for OnPush components if we
want to be backwards compatible with View Engine. This commit re-adds
the legacy logic for OnPush components where events always mark views
dirty and makes it the default behavior.
Note: It is still TODO to add a public API for manual change detection.

In View Engine, we supported @Input and @ContentChild annotations
on the same property. This feature was somewhat brittle because
it would only work for static queries, so it would break if a
content child was passed in wrapped in an *ngIf. Due to the
inconsistent behavior and low usage both internally and externally,
we will likely be deprecating it in the next version, and it does
not make sense to perpetuate it in Ivy.
This commit ensures that we now throw in Ivy if we encounter the
two annotations on the same property.

Fixes components with native content projection (using `<content>` or `<slot>`) not working under Ivy.
The issue comes from the fact that when creating elements inside a component, we sometimes don't append the element immediately, but we leave it to projection to move it into its final destination. This ends up breaking the native projection, because the slots have to be in place from the beginning. The following changes switch to appending the element immediately when inside a component with Shadow DOM encapsulation.
This PR resolves FW-841.

Before this commit we were creating a "fake" TNode for each and every
projectable node passed during dynamic component creation. This approach
had several problems:
- the existing TView structure had to be mutated to accomodate new TNodes and
it was very easy to "corrupt" TView / TNode data structures;
- TNodes are not really needed to fully support projectable nodes so we were
creating objects and updating existing data structures for nothing.
This commit changes the approach so we don't create "fake" TNodes for projectable
nodes but instead we process projectable nodes directly in the projection instruction.
As a result we've got less code, less object allocation and - as a bonus - we fix few
bugs where TView / TNode data structures were corrupted when using projectable nodes.

Initial thinking was that the bug is in the content projection logic but
it turned out to be a wrong assumption - hence adding a test to illustrate
that basic content projection of view containers works correctly.
What fails in the marked test is the logic quering debug nodes - content
peojection is fine but we never create the 'B' text node since we call
show() method on the "wrong" directive instance.

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.

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.

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.

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

that these sementics are true at runtime.
There will need to be seperate set of checks for the AoT path of the

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).
