Migrate over 4.4 lib dom and webworker

[orta]

Finalizes changes from the beta to RC.

[orta]

Most of the changes from the RC are adding deprecated or switching the deprecated to multiline. Though this includes a lot of the beta feedback about the DOM changes in #45047

[orta]

Big changes, but this brings this file up-to-date with the dom.d.ts changes. WebWorker being opt-in meant we focused on the dom changes for the beta and these follow on.

Heya @orta, I've started to run the extended test suite on this PR at 2bba7ee. You can monitor the build here.

The user suite test run you requested has finished and failed. I've opened a PR with the baseline diff from master.

The node12 is from a timeout, which Seems unrelated. Will re-trigger. A lot of the RWC errors seems to have come from the addition of abort to AbortSignal which DefinitelyTyped/DefinitelyTyped#54944 should fix, the same for DT tests.

There's a good question of if we want to ship that change, given that it would force quite a few projects to update their node types version which isn't great.

We're giving Saschanaz a bit of time to see:

• Remove static abort from AbortSignal TypeScript-DOM-lib-generator#1093
• Always emit "| undefined" for optional properties TypeScript-DOM-lib-generator#1092

and a revised:

• Removes the nullable attribute from window.parent TypeScript-DOM-lib-generator#1089

For now I've cherry-picked those 3 PRs into this PR. We can change the types further in the final release of 4.4.
