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.

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.

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
inaccessible outside of it. Animation host listeners in Ivy are
rendered in the context of the parent component, but the VE renders them
differently. This patch ensures that animation host listeners are
always registered in the sub component's renderer

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.

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

This commit creates an API for factory functions which allows them
to be inherited from one another. To do so, it differentiates between
the factory function as a wrapper for a constructor and the factory
function in ngInjectableDefs which is determined by a default
provider.
The new form is:
factory: (t?) => new (t || SomeType)(inject(Dep1), inject(Dep2))
The 't' parameter allows for constructor inheritance. A subclass with
no declared constructor inherits its constructor from the superclass.
With the 't' parameter, a subclass can call the superclass' factory
function and use it to create an instance of the subclass.
For @Injectables with configured providers, the factory function is
of the form:
factory: (t?) => t ? constructorInject(t) : provider();
where constructorInject(t) creates an instance of 't' using the
naturally declared constructor of the type, and where provider()
creates an instance of the base type using the special declared
provider on @Injectable.

To match the View Engine behavior.
We should make this configurable so that the node injector is tree shaken when
directives do not need to be published.

This change supports compilation of components, directives, and modules
within ngtsc. Support is not complete, but is enough to compile and test
//packages/core/test/bundling/todo in full AOT mode. Code size benefits
are not yet achieved as //packages/core itself does not get compiled, and
some decorators (e.g. @Input) are not stripped, leading to unwanted code
being retained by the tree-shaker. This will be improved in future commits.

At runtime in JIT mode, when the compiler writes a reference to a symbol that symbol
is resolved through a symbol table named angularCoreEnv in render3/jit/environment.
Previously, this symbol table was not kept up-to-date with the Ivy instruction set
and the names of symbols the compiler could reference.
This change brings the symbol table in sync, and also adds a test that verifies every
symbol the compiler can reference is available at runtime in the symbol table.
