Misko Hevery e32b6256ce fix(core): `QueryList` should not fire changes if the underlying list did not change. (#40091) 
Previous implementation would fire changes `QueryList.changes.subscribe`
whenever the `QueryList` was recomputed. This resulted in artificially
high number of change notifications, as it is possible that recomputing
`QueryList` results in the same list. When the `QueryList` gets recomputed
is an implementation detail and it should not be the thing which determines
how often change event should fire.

This change introduces a new `emitDistinctChangesOnly` option for
`ContentChildren` and `ViewChildren`.

```
export class QueryCompWithStrictChangeEmitParent {
  @ContentChildren('foo', {
    // This option will become the default in the future
    emitDistinctChangesOnly: true,
  })
  foos!: QueryList<any>;
}
```

public-api/

This directory contains all of the public api goldens for our npm packages we publish to NPM. These are tested on all PRs and commits as part of the our bazel tests.

To check or update the public api goldens, run one of the following commands:

yarn public-api:check
yarn public-api:update

packages-circular-deps.json

This golden file contains a list of all circular dependencies in the project. As part of the lint CI job we compare the current circular dependencies against this golden to ensure that we don't add more cycles. If cycles have been fixed, this file is also updated so that we can slowly burn down the number of cycles in the project.

To check or update the golden, run the following commands:

yarn ts-circular-deps:check
yarn ts-circular-deps:approve
