When testing whether `value` is an object, use the ideal sequence of
strictly not equal to `null` followed by `typeof value === 'object'`
consistently. Specifically there's no point in using double equal with
`null` since `undefined` is ruled out by the `typeof` check.
Also avoid the unnecessary ToBoolean check on `value.ngOnDestroy` in
`hasOnDestroy()`, since the `typeof value.ngOnDestroy === 'function'`
will only let closures pass and all closures are truish (with the
notable exception of `document.all`, but that shouldn't be relevant
for the `ngOnDestroy` hook).

Previously, these components were not added to the view tree for the
(fake) root view in which they were bootstrapped. Without this,
root view destruction does not work as expected since the root view's
children are not present to be also destroyed.

This commit updates test that was added after Content Queries inheritance fix (that renames some instructions) was merged into master. The test used previous version of instructions, thus causing failures after merging Content Queries inheritance fix.
PR Close#28414
Prior to this change contentQueriesRefresh functions that represent refresh logic for @ContentQuery list were not composable, which caused problems in case one Directive inherits another one and both of them contain Content Queries. Due to the fact that we used indices to reference queries in refresh function, results were placed into wrong Queries. In order to avoid that we no longer use indices to reference queries and instead maintain current content query index while iterating through them. This allows us to compose contentQueriesRefresh functions and make inheritance feature work with Content Queries.

By its nature, Ivy alters the import graph of a TS program, adding imports
where template dependencies exist. For example, if ComponentA uses PipeB
in its template, Ivy will insert an import of PipeB into the file in which
ComponentA is declared.
Any insertion of an import into a program has the potential to introduce a
cycle into the import graph. If for some reason the file in which PipeB is
declared imports the file in which ComponentA is declared (maybe it makes
use of a service or utility function that happens to be in the same file as
ComponentA) then this could create an import cycle. This turns out to
happen quite regularly in larger Angular codebases.
TypeScript and the Ivy runtime have no issues with such cycles. However,
other tools are not so accepting. In particular the Closure Compiler is
very anti-cycle.
To mitigate this problem, it's necessary to detect when the insertion of
an import would create a cycle. ngtsc can then use a different strategy,
known as "remote scoping", instead of directly writing a reference from
one component to another. Under remote scoping, a function
'setComponentScope' is called after the declaration of the component's
module, which does not require the addition of new imports.

TestBed.compileComponents has always been an async API. However,
ViewEngine tolerated using this API in a synchronous manner if the
components declared in the testing module did not have any async
resources (templateUrl, styleUrls). This change makes the ivy TestBed
mirror this tolerance by configuring such components synchronously.

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.

Prior to this change the postprocess step relied on the order of placeholders combined in one group (e.g. [�#1�|�*1:1�]). The order is not guaranteed in case we have nested templates (since we use BFS to process templates) and some tags are represented using same placeholders. This change performs postprocessing more accurate by keeping track of currently active template and searching for matching placeholder.

Due to the fast moving nature of the Ivy codebase, the timing isn't
right to make changes to how errors and reported and handled during the
runtime.
Once ivy is stable this test should be revisted because that stage there
will be a better and more robust understanding of how ivy should recover
from runtime errors.

Previous to this change, we were storing view queries at the
wrong index. This is because we were passing a raw index to the
store() instruction instead of an adjusted index (i.e. an
index that does not include the HEADER_OFFSET). We had an
additional issue where TView.blueprint was not backfilled
when TView.data was backfilled, so new component instances
created from the blueprint would end up having a shorter LView.
Both of these problems together led to the Material demo app
failing with Ivy. This commit fixes those discrepancies.

Previously, bootstrapping a component with render3 would create a chained injector with the test bed ngModule instead of the ngModule that the component belongs to.
Now when a component belongs to an ngModule, we use that for the chained injector, ensuring the correct injection of any providers that this ngModule contains.

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.

There are cases where we should check an element injector but don't go
into the associated module injector if a token is not found. In both the
view engine and ngIvy this is acheived by passing the
`NOT_FOUND_CHECK_ONLY_ELEMENT_INJECTOR` as the `notFoundValue`.
Before this fix the view engine and ngIvy were using different objects to
represent `NOT_FOUND_CHECK_ONLY_ELEMENT_INJECTOR`. This was causing problems
as ngUpgrade is using `NOT_FOUND_CHECK_ONLY_ELEMENT_INJECTOR` const in its
`NgAdapterInjector` to prevent searching of module injectors.
This commit makes sure that ngIvy is using the same object to represent
`NOT_FOUND_CHECK_ONLY_ELEMENT_INJECTOR` as the view engine.

Prior to this change `viewQuery` functions that represent @ViewQuery list were not composable, which caused problems in case one Component/Directive inherits another one and both of them contain View Queries. Due to the fact that we used indices to reference queries, resulting query set was corrupted (child component queries were overridden by super class ones). In order to avoid that we no longer use indices assigned at compile time and instead maintain current view query index while iterating through them. This allows us to compose `viewQuery` functions and make inheritance feature work with View Queries.

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.

Fixes Ivy not applying properties that are set in camelCase, because it goes through the `CSSStyleDeclaration` API via `setProperty` and `removeProperty` which requires for [the values to be in dash-case](https://developer.mozilla.org/en-US/docs/Web/API/CSSStyleDeclaration/setProperty).
**Note:** I opted to let the browser normalize the value, rather than convert it to dash-case during compile time, because there are some special cases like browser-prefixed properties where we might not normalize it in-line with the browser.

Previous to this change, the isStylingContext() function was improperly
returning true for LContainers because it used the presence of an array
at index 2 to determine whether it was a styling context. Unfortunately,
LContainers also contain arrays at index 2, so this would return a false
positive. This led to other errors down the line because we would treat
nodes with containers as if they already had styling contexts (even if
they did not), so the proper initialization logic for styling contexts
was not run.
This commit fixes the isStylingContext() function to use LCONTAINER_LENGTH
as a marker rather than the presence of an array, which in turn fixes
host bindings to styles on nodes with containers.

Due to the fact that animations in Angular are defined in the component metadata,
all animation trigger definitions are localized to the component and are

differently. This patch ensures that animation host listeners are
always registered in the sub component's renderer

Prior to this fix Ivy would not execute any animation triggers
that exist as host bindings on an element if it is removed by
the parent template.
PR Close#28162
In Ivy when elements are created a series of static attribute names are provided
over to the construction instruction of that element. Static attribute names
include non-binding attribues (like `<div selected>`) as well as animation bindings
that do not have a RHS value (like `<div @foo>`). Because of this distinction,
value-less animation triggers are rendered first before value-full animation
bindings are and this improper ordering has caused various existing tests to fail.
This patch ensures that animation bindings are evaluated in the order that they
exist within the HTML template code (or host binding code).
