We do this because of a bug caused by https://github.com/evanw/esbuild/issues/2950 and a recent change to how angular static properties are attached to class constructors. Targeting esnext or es2022 will cause the static initializer blocks that attach these static properties on class constructors to reference a class constructor variable that they do not have access to.
Because of this we explicitly target es2020 in our Angular DevTools builds.
PR Close#50086
Since DevTools' Angular framework dependencies are built from local files, they are always up to date. [Recently](https://github.com/angular/angular/pull/49332) these dependencies started being published as fesm2022 instead of fesm2020. We also have an Angular dependency `ngx-flamegraph` that was built and published as fesm2020.
The easiest fix to make sure all of our Angular based dependencies are processed by the linker would be to update the filterPaths field in that file from `/fesm2020/` to `/fesm2020|fesm2022/`. When v16 releases, we can update ngx-flamegraph and publish it with the new APF, letting us change filterPaths to just `/fesm2022/`.

Adds a new AST for a `TransplantedType` in the compiler which will be used for some upcoming work. A transplanted type is a type node that is defined in one place in the app, but needs to be copied to a different one (e.g. the generated .d.ts). These changes also include updates to the type translator that will rewrite any type references within the type to point to the new context file.

Rather than maintaining separate traversal functions that act differently, this change
updates the change detection traversal to share more code and use different modes
to control the type of traversal being performed.

Prior to this commit we tried to retrieve transferred state on both browser and server. Doing this on the server was redundant and could causes issues as `document` might be undefined.
Closes#50138
PR Close#50144
Fixes that the promise returned by `bootstrapApplication` wasn't being rejected when a module imported using `importProvidersFrom` throws an error. The problem was that the function that resolves the providers happens very early as the injector is being constructed.
Fixes#49923.

This commit updates the `@angular/common/http` and `@angular/platform-server` packages to allow dynamic import of the `xhr2` dependency. The `xhr2` dependency has side-effects that rely on a global scope and as a result in some environments those side-effectful calls fail. With the changes from this PR, the import is delayed until it's actually needed, which gives a chance for the underlying platform to setup global scope (via shims) as needed.

Saving and restoring the view is significant enough that it makes sense to handle it independently. This makes for easier reasoning about how view save/restore works.

When ingesting an `ng-template`, inputs might be on the `inputs` or the `templateAttrs` field. More investigation is required to pinpoint the specifics of `templateAttrs`.
For now, we can process them both and generate the appropriate update-mode property instructions.

It's possible to have chains of statements, exclusively in event listeners. A listener with a chain looks like the following:
```
(click)="onClick($event); 1 == 1"
```
We handle this by generating multiple statements, one for each expression in the chain, and only making the final statement the return statement. We place this logic in code specific to listeners, since they are the only place this construct can appear.

We should be able to ingest binary operators. This involves parsing the left and right ASTs, and converting the operator string to a logical `BinaryOperator`.

ElementContainer instructions refer to `ng-container` element tags, which don't produce corresponding DOM nodes. Much like element instructions, container instructions can also have their start and end tags combined.
