5892579440 Build/Test Tools: Support NodeJS 14.x in the 4.9 branch. 
This updates the 4.9 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.

This also replaces the `npm-shrinkwrap.json` with a `package-lock.json` file. Lock files were not supported in earlier versions of NPM, but can now be used.

In addition to backporting the package updates that happened after branching 4.9, dependencies that were removed in future releases have also been updated to their latest versions.

Props desrosj, dd32, netweb, jorbin.

691d649329 Media: Remove the custom styling for the MediaElementJS controls offscreen text.

Also, revealing it on focus has proven over time to be very fragile and to cause
unexpected layout issues.

3d8e31fb82 Don't hardcode height for videos - this was a workaround for MediaElement internals causing problems. Responsive videos now work properly and don't cause extra whitespace. 
Fixes MediaElement by hand in the interim: https://github.com/johndyer/mediaelement/pull/1337
Video playlists were completely broken by this.

Fixes #30078.

149346ff6e MCE View sandboxes: 
* Use a `MutationObserver` to listen to the `body` class of the parent editor frame.
* In `wpview_media_sandbox_styles()`, only return the MEjs stylesheets.
* In `wp_ajax_parse_media_shortcode()` and `wp_ajax_parse_embed()`, return an object instead of an HTML blob to allow passing `body` and `head` separately	

Props avryl, azaozz.
