These helpers are often imported by various tests throughout the
repository, but the helpers aren't exported/exposed from the public
entry-point; even though they confusingly reside in there.
This commit fixes this, and moves the helpers into
`packages/private/testing`. This is a preparation for the `ts_project`
migration where we don't want to leverage deep imports between packages.

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.

Fixes#14638
Uses Domino - https://github.com/fgnass/domino and removes dependency on
Parse5.
The DOCUMENT and nativeElement were never typed earlier and were
different on the browser(DOM nodes) and the server(Parse5 nodes). With
this change, platform-server also exposes a DOCUMENT and nativeElement
that is closer to the client. If you were relying on nativeElement on
the server, you would have to change your code to use the DOM API now
instead of Parse5 AST API.
Removes the need to add services for each and every Document
manipulation like Title/Meta etc.
This does *not* provide a global variable 'document' or 'window' on the
server. You still have to inject DOCUMENT to get the document backing
the current platform server instance.
