Alex Rickabaugh 113556357a fix(ivy): compute transitive scopes from NgModuleDef only (#24334)
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.

Alex Rickabaugh 7983f0a69b ci(ivy): configure CI environments for Ivy JIT and AOT (#24309)
Two new CircleCI environments are created: test_ivy_jit and test_ivy_aot.
Both run a subset of the tests that have been marked with Bazel tags as
being appropriate for that environment.

Once all the tests pass, builds are published to the *-builds repo both
for the legacy View Engine compiled code as well as for ivy-jit and ivy-aot.

This PR tackles a simple case where ViewRef definition point (<ng-template>) is the

Pawel Kozlowski 90bf5d8961 feat(ivy): separate attributes for directive matching purposes (#23991)
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.

Alex Rickabaugh 1eafd04eb3 build(ivy): support alternate compilation modes to enable Ivy testing (#24056)
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.

Victor Berchet 4f36340de7 feat(ivy): add support for short-circuiting (#24039)
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.

Misko Hevery da31db757b feat(ivy): support injection even if no injector present (#23345)
- 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
  pass as well as enable `IterableDiffers` to be injectable without
  `Injector`

Miško Hevery 3fb4e190a8 fix(ivy): correctly bind to component context (#23168)
When compiling templates the compiler would often bind to
closest context rather than the component context.

The only time one should be binding to the cont component is
in explicit cases where the inner template declares local variable.

Pawel Kozlowski d80e9304c6 fix(ivy): properly find RNode (#23193)
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).
