Alex Rickabaugh fefc860f35 fix(ivy): fix bug with banana-in-a-box expressions in nested templates (#25321)
Inside of a nested template, an attempt to generate code for a banana-
in-a-box expression would cause a crash in the _AstToIrVisitor, as it
was not handling the case where a write would be generated to a local
variable.

This change supports such a mode of operation.

Michael Giambalvo 16c03c0f38 fix(core): In Testability.whenStable update callback, pass more complete (#25010)
data about tasks.

When building a list of pending tasks for callers of whenStable(),
Testability will copy data about the task into a new object, in order to
avoid leaking references to tasks.

This change copies more properties from Tasks into the list of pending
tasks, as well as a reference to Task.data to give callers more
information about the tasks that are pending.

Specifically, this also copies runCount and task ID, which are needed in
order for callers to know when a given task is repeating.

Alex Rickabaugh eb999300d9 test(ivy): run compiler compliance tests without rebuilding core,common (#25248)
Previously the compiler compliance tests ran and built test code with
real dependencies on @angular/core and @angular/common. This meant that
any changes to the compiler would result in long rebuild processes
for tests to rerun.

This change removes those dependencies and causes test code to be built
against the fake_core stub of @angular/core that the ngtsc tests use.
This change also removes the dependency on @angular/common entirely, as
locality means it's possible to reference *ngIf without needing to link
to an implementation.

.ngfactory files, which Ivy does not need. This commit adds the

Misko Hevery aafd502bcb fix(ivy): default to `ngDevMode = true` (#25208)
Before the `ngDevMode` had to be set explicitly or it would throw
an exception at runtime. This changes it so that if `ngDevModu` is
`undefined` than we default to `ngDevMode = true`. In other words
unless the developer has explicitly asked to make a prodution build
by setting `ngDevMode = false` as compilation constant, the default
is `ngDevMode = true`.

This also fixes a minor bug where the setup code would read
`global['ngDevMode']` but all other code would read `global.ngDevMode`.
This would cause issues with closure compiler since the
reading of the `ngDevMode` must be consistent.

Carlos Ortiz Garcia e99d860393 feat(compiler): add "original" placeholder value on extracted XMB (#25079)
Update XMB placeholders(<ph>) to include the original value on top of an
example. Placeholders can by definition have one example(<ex>) tag and a
text node. The text node is used by TC as the "original" value from the
placeholder, while the example should represent a dummy value.
For example: <ph name="PET"><ex>Gopher</ex>{{ petName }}</ph>.
This change makes sure that we have the original text, but it *DOES NOT*
make sure that the example is correct. The example has the same wrong
behavior of showing the interpolation text rather than a useful
example.

No breaking changes, but tools that depend on the previous behavior and
don't consider the full XMB definition may fail to parse the XMB.

Alex Rickabaugh 3169edd77a fix(ivy): don't crash in listLazyRoutes() (#25080)
This commit replaces the "not implemented" error when calling
listLazyRoutes() with an empty result, which will allow testing
in the CLI before listLazyRoutes() is implemented.

Alex Rickabaugh 8de304c15a fix(ivy): wait for preanalyze promises in loadNgStructureAsync() (#25080)
loadNgStructureAsync() for ngtsc has a bug where it returns a
Promise<Promise[]> instead of awaiting the entire array of Promises.

This commit uses Promise.all() to await the whole set.

Alex Rickabaugh 0d1d5898e3 fix(bazel): allow compile_strategy to be (privately) imported (#25080)
compile_strategy() is used to decide whether to build Angular code
using ngc (legacy) or ngtsc (local). In order for g3 BUILD rules
to switch properly and allow testing of Ivy in g3, they need to
import this function.

This commit removes the _ prefix which allows the function to be
imported.

Alex Rickabaugh e0c0c44d99 fix(ivy): allow relative imports of .d.ts files (#25080)
ngtsc used to assume that all .d.ts dependencies (that is, third party
packages) were imported via an absolute module path. It turns out this
assumption isn't valid; some build tools allow relative imports of
other compilation units.

In the absolute case, ngtsc assumes (and still does) that all referenced
types are available through the entrypoint from which an @NgModule was
imported. This commit adds support for relative imports, in which case
ngtsc will use relative path resolution to determine the imports.

Alex Rickabaugh 13a0d527f6 fix(ivy): correctly write cross-file references (#25080)
There is a bug in the existing handling for cross-file references.
Suppose there are two files, module.ts and component.ts.

component.ts declares two components, one of which uses the other.
In the Ivy model, this means the component will get a directives:
reference to the other in its defineComponent call.

That reference is generated by looking at the declared components
of the module (in module.ts). However, the way ngtsc tracks this
reference, it ends up comparing the identifier of the component
in module.ts with the component.ts file, detecting they're not in
the same file, and generating a relative import.

This commit changes ngtsc to track all identifiers of a reference,
including the one by which it is declared. This allows toExpression()
to correctly decide that a local reference is okay in component.ts.

Alex Rickabaugh ed7aa1c3e5 fix(ivy): force new imports for .d.ts files (#25080)
When ngtsc encounters a reference to a type (for example, a Component
type listed in an NgModule declarations array), it traces the import
of that type and attempts to determine the best way to refer to it.

In the event the type is defined in the same file where a reference
is being generated, the identifier of the type is used. If the type
was imported, ngtsc has a choice. It can use the identifier from the
original import, or it can write a new import to the module where the
type came from.

ngtsc has a bug currently when it elects to rely on the user's import.
When writing a .d.ts file, the user's import may have been elided as
the type was not referred to from the type side of the program. Thus,
in .d.ts files ngtsc must always assume the import may not exist, and
generate a new one.

In .js output the import is guaranteed to still exist, so it's
preferable for ngtsc to continue using the existing import if one is
available.

This commit changes how @angular/compiler writes type definitions, and
allows it to use a different expression to write a type definition than
is used to write the value. This allows ngtsc to specify that types in
type definitions should always be imported. A corresponding change to
the staticallyResolve() Reference system allows the choice of which
type of import to use when generating an Expression from a Reference.
