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.

Previously ngtsc had a few bugs handling special token types:
* Injector was not properly translated to INJECTOR
* ChangeDetectorRef was not injected via injectChangeDetectorRef()
This commit fixes these two bugs, and also adds a test to ensure
they continue to work correctly.

On accident a few of the definition types were emitted as public API
symbols. Much of the Ivy API surface is still prefixed with ɵ,
indicating it's a private API. The definition types should be private
for now.

This updates the r3_pipe_compiler to not depend on global analysis,
and to produce ngPipeDef instructions in the same way that the other
compilers do. It's a precursor to JIT and AOT implementations of
@Pipe compilation.

- Adds InheritanceDefinitionFeature to ivy
- Ensures that lifecycle hooks are inherited from super classes whether they are defined as directives or not
- Directives cannot inherit from Components

- Ensures that super class Features are run

This change generates ngInjectorDef as well as ngModuleDef for @NgModule
annotated types, reflecting the dual nature of @NgModules as both compilation
scopes and as DI configuration containers.
This required implementing ngInjectorDef compilation in @angular/compiler as
well as allowing for multiple generated definitions for a single decorator in
the core of ngtsc.

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.

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.
PR Close#24039
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.
PR Close#23833
Previously, the compileComponent() and compileDirective() APIs still required
the output of global analysis, even though they only read local information
from that output.
With this refactor, compileComponent() and compileDirective() now define
their inputs explicitly, with the new interfaces R3ComponentMetadata and
R3DirectiveMetadata. compileComponentGlobal() and compileDirectiveGlobal()
are introduced and convert from global analysis output into the new metadata
format.
This refactor also splits out the view compiler into separate files as
r3_view_compiler_local.ts was getting unwieldy.
Finally, this refactor also splits out generation of DI factory functions
into a separate r3_factory utility as the logic is utilized between different
compilers.

This commit adds a new compiler pipeline that isn't dependent on global
analysis, referred to as 'ngtsc'. This new compiler is accessed by
running ngc with "enableIvy" set to "ngtsc". It reuses the same initialization
logic but creates a new implementation of Program which does not perform the
global-level analysis that AngularCompilerProgram does. It will be the
foundation for the production Ivy compiler.

This change changes:
- compiler uses `directiveInject` instead of `inject` for `Directive`s
- unifies the flags in `di` as well as `render3`
- changes the signature of `directiveInject` to match `inject` In prep for #23330
- compiler now generates flags for injection.

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

This adds compilation of @NgModule providers and imports into

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.
