Fixes Ivy not throwing an error if it runs into an invalid property binding on a container node (e.g. `<div *ngFor="let row of rows">` instead of `<div *ngFor="let row if rows">`).
This PR resolves FW-1219.

In some cases ivy expects projectable nodes to be passed in a different order
to ViewEngine. Specifically, ivy expects the catch-all ("*") to be at index
0, whereas ViewEngine expects it to be at its position at which it was parsed
in the template.
This commit adds one test that breaks under ivy and others that just describe
more accurately what happens in corner cases.

Prior to this change, we always recompile all Components/Directives/Pipes even if they were AOT-compiled and had no overrides. This is causing problems in case we try to recompile a Component with "templateUrl" or "styleUrls" (which were already resolved in case of AOT) and generally this unnecessary work that TestBed was doing is not required. This commit adds extra logic to check whether a Component/Directive/Pipe already have compiled NG def (like ngComponentDef) and whether there are no overrides present - in this case recompilation is skipped. Recompilation is also skipped in case a Component/Directive has only Provider overrides - in this situation providers resolver function is patched to reflect overrides. Provider overrides are very common in g3, thus this code path ensures no full recompilation.

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.

There are some differences in how ivy maps template source
compared to View Engine. In this commit we recreate the View Engine
tests for ivy.

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.

There is nothing browser specific in those tests and fakeAsync is supported on node.

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.

NullInjectorError: No provider for SportsCar!

Fixes Ivy not passing thrown errors along to the `ErrorHandler`.
**Note:** the failing test had to be reworked a little bit, because it has some assertions that depend on an error context being logged, however Ivy doesn't keep track of the error context.

PR Close#28447
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.
PR Close#28474
Due to the fact that the test in 'ng_module_integration_spec.ts' relied on internal VE data structures (the '_def' field) to verify the state and the structure has changed in Ivy, this commit adds an Ivy version of the same test.
PR Close#28477
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.

Prior to this change we may encounter some errors (like pipes being used where they should not be used) while compiling Host Bindings and Listeners. With this update we move validation logic to the analyze phase and throw an error if something is wrong. This also aligns error messages between Ivy and VE.

This commit unifies handling of the "check no changes" mode between
ngIvy and the view engine. More specifically:
- check no changes can be invoked before change detection in ivy;
- `undefined` values are considered equal `NO_CHANGES` for the "check no changes"
mode purposes.
Chanes in this commit enables several tests that were previously running only in ivy
or only in the view engine.

DebugElement.properties should contain a map of element
property names to element property values, with entries
for both normal property bindings and host bindings.
Many Angular core tests depend on this map being present.
This commit adds support for host property bindings in
DebugElement.properties, which fixes the Angular core tests.
There is still work to be done for normal property bindings.

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.
