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.

Bazel has a restriction that a single output (eg. a compiled version of
//packages/common) can only be produced by a single rule. This precludes
the Angular repo from having multiple rules that build the same code. And
the complexity of having a single rule produce multiple outputs (eg. an
ngc-compiled version of //packages/common and an Ivy-enabled version) is
too high.
Additionally, the Angular repo has lots of existing tests which could be
executed as-is under Ivy. Such testing is very valuable, and it would be
nice to share not only the code, but the dependency graph / build config
as well.
Thus, this change introduces a --define flag 'compile' with three potential
values. When --define=compile=X is set, the entire build system runs in a
particular mode - the behavior of all existing targets is controlled by
the flag. This allows us to reuse our entire build structure for testing
in a variety of different manners. The flag has three possible settings:
* legacy (the default): the traditional View Engine (ngc) build
* local: runs the prototype ngtsc compiler, which does not rely on global
analysis
* jit: runs ngtsc in a mode which executes tsickle, but excludes the
Angular related transforms, which approximates the behavior of plain
tsc. This allows the main packages such as common to be tested with
the JIT compiler.
Additionally, the ivy_ng_module() rule still exists and runs ngc in a mode
where Ivy-compiled output is produced from global analysis information, as
a stopgap while ngtsc is being developed.

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

Currently the context for inject() is only set when the token is seen
for the first time. This has two issues:
* It should always be set when injecting from that injector, because
a constructor may wish to call inject() directly.
* If an NgModuleFactory is .create()'d twice, and an ngInjectableDef
token is requested from each of them, the second time will fail.
This is because the first injection adds the provider definition
and calls the factory, and the provider definitions are shared.
The second injector will see the provider definition and call the
factory to create an instance, but without setting the correct
context for inject().

This lets projects like Material change ng_package "bundle index" files to non-conflicting paths
Currently packages like @angular/core ship with the generated metadata
in a path like 'core.js' which overwrites one of the inputs.
Angular material puts the generated file in a path like 'index.js'
Either way these files generated by ng_module rules have the potential
to collide with inputs given by the user, which results in an error.
Instead, give users the freedom to choose a different non-conflicting name.
Also this refactors the ng_package rule, removing the redundant
secondary_entry_points attribute.
Instead, we assume that any ng_module in the deps with a module_name
attribute is a secondary entry point.

The crux of the bug was that we were looking for a view to update

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

@Injectable() supports a scope parameter which specifies the target module.
However, it's still difficult to specify that a particular service belongs

Both of these strategies are cumbersome and brittle.
