Hide Video block toggles for Autoplay and Plays Inline

[westonruter]

Extracted from #2255, where default values have been provided for autoplay and playsinline, but what is remaining:

• The Autoplay toggle for the Video block needs to be hidden/removed in AMP Stories, because autoplay is required.
• The "Play Inline" toggle for the Video block needs to be hidden/removed always since it is not allowed in AMP.

These depend on WordPress/gutenberg#6023.

I just noticed that the order of panels in the block sidebar is different right after inserting a block vs. when selecting it later. Since the CSS relies on that order, the toggles are sometimes still visible.

Just inserted:

Selected later:

Would be good to have some consistency here. I suppose we need to work with some filter priorities.

Looks like that's a Gutenberg issue...

Opened an issue upstream to get some feedback: WordPress/gutenberg#15641

Maybe this can be fixed by changing the order in which the components are wrapped/returned. Will have to try it out.

Since this has been tested in #2109, and WordPress/gutenberg#15641 is something I haven't been able to find a workaround for, I'm closing this for now.
