When setting `"useDefineForClassFields": false`, static fields are compiled within a block that relies on the `this` context. This output makes it more difficult for bundlers to treeshake and eliminate unused code.

The keyvalue pipe sorts the entries of the input by key. This has been the subject of debate in the past (https://github.com/angular/angular/issues/42490). The core of the discussions is that it is often desirable (and perhaps expected) that they natural ordering of the input is respected. There are at least two workarounds to restore natural ordering, such as a `compareFn` that simply returns `1` or a custom pipe. However, both of these require code for pipe consumers to maintain or copy around to many places.
Allowing `null` as `compareFn` and treating it as "natural order" is fairly simple to understand, backward compatible and was suggested a few times on https://github.com/angular/angular/issues/42490 where it seemed to be received well. Using `null` is also possible in templates without any component code changes.

This commit removes the testability features that are internal only.
This simplifies the implementation of testability which will need
updates to support zoneless. Those updates will be easier to manage if
the Testability implementation is simpler.
While protractor is indeed officially EOL, we will still need to do some
updates to support teams migrating to zoneless that have protractor
tests.
As far as protractor's own use of `whenStable`, it does not read the
internal only methods either:
https://github.com/angular/protractor/blob/master/lib/clientsidescripts.js
Anything else depending on these values are not following the defined public API
contract.
