A lot of our tests are wrapped in `{}` which serves no purpose, aside from increasing the nesting level and, in some cases, causing confusion. The braces appear to be a leftover from a time when all tests were wrapped in a `function main() {}`. The function declaration was removed in #21053, but the braces remained, presumably because it was easier to search&replace for `function main()`, but not to remove the braces at the same time.

This adds `generate_api_docs` targets to all of the packages for which we publish api reference docs. One known issue here is that any type information that comes from another package (e.g. router depending on core) currently resolve to `any` because the other sources are not available in the program. This can be tackled in a follow-up commit.
This commit also updates the install patch for `@angular/build-tools` to use the local version of compiler-cli.

BREAKING CHANGE: Node.js v16 support has been removed and the minimum support version has been bumped to 18.13.0.

According to the HTML specification most attributes are defined as strings, however some can be interpreted as different types like booleans or numbers. [In the HTML standard](https://html.spec.whatwg.org/multipage/common-microsyntaxes.html#boolean-attributes), boolean attributes are considered `true` if they are present on a DOM node and `false` if they are omitted. Common examples of boolean attributes are `disabled` on interactive elements like `<button>` or `checked` on `<input type="checkbox">`. Another example of an attribute that is defined as a string, but interpreted as a different type is the `value` attribute of `<input type="number">` which logs a warning and ignores the value if it can't be parsed as a number.
Historically, authoring Angular inputs that match the native behavior in a type-safe way has been difficult for developers, because Angular interprets all static attributes as strings. While some recent TypeScript versions made this easier by allowing setters and getters to have different types, supporting this pattern still requires a lot of boilerplate and additional properties to be declared. For example, currently developers have to write something like this to have a `disabled` input that behaves like the native one:
```typescript
import {Directive, Input} from '@angular/core';
@Directive({selector: 'mat-checkbox'})
export class MatCheckbox {
@Input()
get disabled() {
return this._disabled;
}
set disabled(value: any) {
this._disabled = typeof value === 'boolean' ? value : (value != null && value !== 'false');
}
private _disabled = false;
}
```
This feature aims to address the issue by introducing a `transform` property on inputs. If an input has a `transform` function, any values set through the template will be passed through the function before being assigned to the directive instance. The example from above can be rewritten to the following:
```typescript
import {Directive, Input, booleanAttribute} from '@angular/core';
@Directive({selector: 'mat-checkbox'})
export class MatCheckbox {
@Input({transform: booleanAttribute}) disabled: boolean = false;
}
```
These changes also add the `booleanAttribute` and `numberAttribute` utilities to `@angular/core` since they're common enough to be useful for most projects.

`setDisabledState` is supposed to be called whenever the disabled state of a control changes, including upon control creation. However, a longstanding bug caused the method to not fire when an *enabled* control was attached. This bug was fixed in v15.
This had a side effect: previously, it was possible to instantiate a reactive form control with `[attr.disabled]=true`, even though the the corresponding control was enabled in the model. (Note that the similar-looking property binding version `[disabled]=true` was always rejected, though.) This resulted in a mismatch between the model and the DOM. Now, because `setDisabledState` is always called, the value in the DOM will be immediately overwritten with the "correct" enabled value.
Users should instead disable the control directly in their model. (There are many ways to do this, such as using the `{value: 'foo', disabled: true}` constructor format, or immediately calling `FooControl.disable()` in `ngOnInit`.)
If this incompatibility is too breaking, you may also opt out using `FormsModule.withConfig` or `ReactiveFormsModule.withConfig` at the time you import it, via the `callSetDisabledState` option.
However, there is an exceptional case: radio buttons. Because Reactive Forms models the entire group of radio buttons as a single `FormControl`, there is no way to control the disabled state for individual radios, so they can no longer be configured as disabled.
In this PR, we have special cased radio buttons to ignore their first call to `setDisabledState` when in `callSetDisabledState: 'always'` mode. This preserves the old behavior.

Tests now always run with ESM 2020, while previously they ran with
ES2015 CommonJS UMD bundles.
Since ZoneJS does not support intercepting native `async/await` syntax,
the forms test needs to use the zone-compatible variant of
`jasmine_node_tests`. This variant downlevels the native `async/await`
syntax to generators that ZoneJS can intercept. All of this is done
using the dev-infra ESBuild `spec_bundle` rule.

Since we generate a `.mjs` file as entry-point for jasmine tests,
a couple of issues prevented the transitive dependencies from
bootstrap targets to be brought in (causing resolution errors):
1. The `_files` (previously `_esm2015`) targets are no longer needed,
and they also miss all the information on runfiles.
2. The aspect for computing linker mappings does not respect the
`bootstrap` attribute from the `spec_entrypoint` so we manually
add the extract ESM output targets (this rule works with the aspect
and forwards linker mappings).
PR Close#48521
For every `ts_library` target we expose a shorthand that grants
access to the JS files because `DefaultInfo` of a ts library
only exposes the `.d.ts` files.
We rename this away from `es2015` since in practice it's a much
higher target these days. Additionally we no longer use the devmode
output but rather use the prodmode output which has the explicit
`.mjs` output- compatible with ESM.
