This updates the 4.0 branch to support the latest LTS version of NodeJS (currently 14.x), allowing the same version to be used across all WordPress branches that receive security updates as a courtesy.
Because older branches use (really) old versions of NodeJS, the local Docker environment cannot be backported since the needed dependencies will not run on these older versions (see #48301). This also blocks the ability to move automated testing over to GitHub Actions (see #50401).
This change also introduces a `packager-lock.json` file to the branch.
In addition to backporting the package updates that happened after branching 4.0, dependencies that were removed in future releases have also been updated to their latest versions.

* Re-work how and when widget forms get updated.
* Replace ad hoc hooks system with jQuery events,
* Add `widget-updated`/`widget-synced` events for widget soft/hard updates.
* Enter into a non-live form update mode, where the Apply button is restored when a sanitized form does not have the same fields as currently in the form, and so the fields cannot be easily updated to their sanitized values without doing a complete form replacement. Also restores live update mode if sanitized fields are aligned with the existing fields again.
Note: jQuery events are *not* final yet, see #19675.
