…-out Currently when compiling code with the Angular compiler, all classes with Angular decorators are compiled with AOT. This includes type checking, scope collection etc. This may not be desirable for all components, e.g. dynamic components, or test components w/ `TestBed.configureTestingModule` (if compiled with ngtsc). Those components can opt out of AOT on a per component-basis via `jit: true`. This is helpful as it allows incremental migrations/refactorings to AOT. Whether we want to keep this capability long-term is something to be discussed separately. For now though, we should fix that components compiled with `jit: true` actually work as expected. Currently this **not the case** as soon as the new initializer APIs are used— as those do no longer declare class metadata with decorators. This commit runs the JIT transform on JIT-opted classes.

This commit moves the JIT transforms into the ngtsc folder. They existed outside of ngtsc mostly as an historic artifact— and now with compiler relying on them even more deeply, it makes sense to move them into `ngtsc/transform`.

Currently when compiling code with the Angular compiler, all classes
with Angular decorators are compiled with AOT. This includes type
checking, scope collection etc.
This may not be desirable for all components, e.g. dynamic components,
or test components w/
TestBed.configureTestingModule(if compiled with ngtsc).Those components can opt out of AOT on a per component-basis via
jit: true.This is helpful as it allows incremental migrations/refactorings to AOT.
Whether we want to keep this capability long-term is something to be discussed separately.
For now though, we should fix that components compiled with
jit: trueactually work as expected. Currently this not the case as soon as
the new initializer APIs are used— as those do no longer declare class
metadata with decorators.
This commit runs the JIT transform on JIT-opted classes.
