⚠️Disclaimer⚠️ this PR implements syntax that is still in an open RFC. It will be adjusted once the RFC is closed.
These changes extend the lexer to recognize the concepts of a block group (`{#foo paramA; paramB}{/foo}`) and a block (`{:foo paramA; paramB;}`) which will be useful later on for the control flow and defer proposals. Block groups can be used anywhere and require a closing tag while block can only be used inside of a block.
The idea is that in the next PRs the markup AST will be expanded to have some more specialized node like `ConditionalBlock` or `DeferBlock` which will then be turned into instructions.

This commit adds the ability to generate attribute instructions as a result of property bindings such as `[attr.foo]='bar'` or `attr.foo='{{bar}}'`. "Singleton" interpolations, such as the previous example, will also be transformed into a simple `attribute` instruction.

Prior to this change, we've used `componentDef.id` as a key in a Map that acts as a cache to avoid re-creating injector instances for standalone components. In v16, the logic that generates the id has changed from an auto-incremental to a generation based on metadata. If multiple components have similar metadata, their ids might overlap.
This commit updates the logic to stop using `componentDef.id` as a key and instead, use the `componentDef` itself. This would ensure that we always have a correct instance of an injector associated with a standalone component instance.
Resolves#50724.

The option 'local compile' is added for the test cases, and the locally compiled file for an input `abc.ts` is compared by default with the file `abc.local.js`. This allows to use the same input `abc.ts` for both full compilation (compared with `abc.js`) and local compilation (compared with `abc.local.js`). An example is provided in the next commit when compliance tests are added for the NgModule local compilation.

The new interface is discrete-unioned with the existing interface to cover the cases for local and global (i.e., full and partial) compilation modes.
This change of interface required some adjustmeents cross repo which explains the changes made to other files.

All attempts related to obtaining R3Reference for bootstrap, imports, exports and declarations are cut in local compilation mode.
This will allow the analysis to pass without any error diagnostics, but the result is a quite empty meta info. Next commits will add data to the meta so that the NgModule can be compiled more accurately.

In the past, we had an implementation of the "Angular 2" router that
also worked with AngularJS. Published as `@angular/router`. We continued
to expose that router implementation in G3 and some applications still
use it. Now, when upgrading, they are seeing issues where the router
throws because it cannot find a route config/ or `$canActivate` on the
controller- simply because there is no `controller` function for
downgraded components.
We can fix this and unblock the update by simply ensuring a controller
function is defined.

Previously, the template pipeline save/restore view logic only added the
save/restore operation in listeners inside embedded views. However, this
operation is also needed if local refs are accessed within a listener body.
This commit updates the logic to detect more accurately whether save/restore
is needed.

This commit updates the implementation of the `getNativeRequestAnimationFrame`
and checks whether the current code runs in the browser before retrieving
`requestAnimationFrame`. `requestAnimationFrame` is not available when the code
is running in the Node.js environment. We have to fallback to `setTimeout` for
delaying the change detection.

Even though the action is already guarded to only run for
organization members that manually trigger the action, we
can reduce the permissions by using a GitHub token without
any permissions to post the result comment.
The expression `a()?.b` should expand into `(tmp = a()) === null ? null : tmp.b`, in order to avoid calling the function `a()` twice.
This commit modifies the null-safe-expansion algorithm to emit temporary assignments, and provides the reification code to actually generate the declarations, assignments, and reads.
Note also that, with our bottom-up algorithm, there are some tricky cases when a function call exists inside an indexed access, such as `f1()?.[f2()?.a]?.b`. We add some special logic to avoid generating a double-assignment to the temporary storing the result of `f2()`.
Finally, there are opportunities to reuse the same temporary in expressions like `a?.[f()]?.[f()]`. We save this for the next commit.

Prior to this commit, the renderer destroy method was being called before the animation complete. This is problematic when using `REMOVE_STYLES_ON_COMPONENT_DESTROY` as it causes the styles to be removed too early.
This commit, updates this destroy logic to be call the render destroy once the animations complete.
