Gutenberg: Audit experimental feature usage.

[sirreal]

There are many experimental features in use right now. Audit them. See docs about these APIs.

This is a master tracking issue for the following:

• Editing Toolkit: Audit experimental features in Editing Toolkit #46489
• WPCOM Block Editor: Audit experimental features in WPCOM Block Editor #46494
• WordPress Components Gallery: Audit experimental features in WordPress Components Gallery #46496

Milestone: https://github.com/Automattic/wp-calypso/milestone/324
Gutenberg Experimental API Audit: WordPress/gutenberg#25786

Do we need to watch __unstable as well?

Make sure they don't break when the experimental feature goes away (undefined errors, etc), ping the right people about that, see if issues need to be created. Perhaps the best way would be to start with a P2 post.

Do we need to watch __unstable as well?

Found just one occurrence here. Added to the Editing Toolkit tracking issue.

@WunderBart Can you compare our feature usage with WordPress/gutenberg#25786? That should help give us an idea of what things are priorities.
