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.

When creating content queries from a directive on an element we need to take into account
existing view queries. The same element can be reported to both content and view queries
so freshly created content queries must be combined with pre-existing view queries.

Previously, the transitive scopes of an NgModuleDef were computed
during execution of the @NgModule decorator. This meant that JIT-
compiled modules could only import other JIT-compiled modules, as
the import mechanism relied on the calculation of transitive scopes
to already have happened for the imported module.
This change moves computation of transitive scopes to a function
`transitiveScopesFor` (and makes it lazy). This opens the door for
AOT -> JIT or JIT -> AOT imports, as transitive scopes for AOT
modules can be calculated when needed by JIT, and AOT modules can
also write expressions that call `transitiveScopesFor` when
importing a JIT-compiled module.

`NgForOf` used to implement `OnChanges` and than use
`ngOnChanges` callback to detect when `ngForOf` binding
changed to update the differ. We now do the checking
manually which puts less pressure on the runtime to do
the bookkeeping and should result in minor perf improvement.

This PR tackles a simple case where ViewRef definition point (<ng-template>) is the
same as the insertion point (ViewContainerRef requested on the said <ng-template>).
For this particular case we can assume that we know a container into which a given
view will be inserted when a view is created. This is not true fall all the possible
cases so follow-up PR will be needed to extend this basic implementation.

In ngIvy directives matching (determining which directives are active based
on a CSS seletor) happens at runtime. This means that runtime needs to have
enough context to match directives. This PR takes care of cases where a directive's
selector should match bindings (ex. [foo]="exp") and event handlers (ex. (out)="do()").
In the mentioned cases we need to have binding / output "attributes" for directive's
CSS selector matching purposes. At the same time those are not regular attributes and
as such should not be reflected in the DOM.
Closes#23706
PR Close#23991
Short-circuitable expressions (using ternary & binary operators) could not use
the regular binding mechanism as it relies on the bindings being checked every
single time - the index is incremented as part of checking the bindings.
Then for pure function kind of bindings we use a different mechanism with a
fixed index. As such short circuiting a binding check does not mess with the
expected binding index.
Note that all pure function bindings are handled the same wether or not they
actually are short-circuitable. This allows to keep the compiler and compiled
code simple - and there is no runtime perf cost anyway.

This commit adds a mechanism by which the @angular/core annotations
for @Component, @Injectable, and @NgModule become decorators which,
when executed at runtime, trigger just-in-time compilation of their
associated types. The activation of these decorators is configured
by the ivy_switch mechanism, ensuring that the Ivy JIT engine does
not get included in Angular bundles unless specifically requested.

The bug fixed here steams from the fact that we are traversing too far up
in the views tree hierarchy in the destroyViewTree function.
The logic in destroyViewTree is off if we start removal at an embedded view
without any child views. For such a case we should just clean up (cleanUpView)
this one view without paying attention to next / parent views.

Ivy definition looks something like this:
```
class MyService {
static ngInjectableDef = defineInjectable({
…
});
}
```
Here the argument to `defineInjectable` is well known public contract which needs
to be honored in backward compatible way between versions. The type of the
return value of `defineInjectable` on the other hand is private and can change
shape drastically between versions without effecting backwards compatibility of
libraries publish to NPM. To our users it is effectively an opaque token.
For this reson why declare the return value of `defineInjectable` as `never`.

- Remove default injection value from `inject` / `directiveInject` since
it is not possible to set using annotations.
- Module `Injector` is stored on `LView` instead of `LInjector` data
structure because it can change only at `LView` level. (More efficient)
- Add `ngInjectableDef` to `IterableDiffers` so that existing tests can

As we no longer create native (RNode) comment nodes for containers,
we need to execute logic for finding a next sibiling node with RNode
when inserting a view.
The mentioned logic need to be updated for the case of dynamically
created containers (LContainerNode). Indeed, we need to be able to
descend into dynamically inserted views while looking for a RNode.
To achieve this we need to have a pointer from a host LNode to a
dynamically created LContainerNode).

Generate directives as a list in `componentDef` rather than inline into

Adds a stub for `elementStyle` and `elementClass` instruction

Rename:
- `elementClass` (short: `k`) => `elementClassNamed` (short: `kn`)
- `elementStyle` (short: `s`) => `elementStyleNamed` (short: `sn`)
Currently `[class.name]` is `elementClass(0, ‘name’, value)`. We would
like to introduce new binding `[class]` which needs a new instruction
ideally `elementClass(0, value)`. Doing the rename creates space
to create such an instruction in subsequent change.

This commit fixes a bug that would result in views insert / remove
even if a view needed only refresh operation.
The crux of the bug was that we were looking for a view to update
only in the LContainer.nextIndex position. This is incorrect as a
view with a given block id could be present later in the views
array (this happens if we about to remove a view in the middle of
the views array).
The code in this fix searches for a view to update in the views array and
can remove views in the middle of the views collection. Previously we
would remove views at the end of the collection only.
