Make video autoplay configurable
[https://discord.com/channels/859816885297741824/1352250745889751142/1352250745889751142](https://discord.com/channels/859816885297741824/1352250745889751142/1352250745889751142)<br><br>I'd suggest one or two things

1. add an 'autoplay' prop to the video props
2. (maybe) add an 'autoplayByDefault' option to the editor options bag that we use when adding new video shapes

if we don't do 2 then people will have to implement it themselves with side effects, which would be a pain in the butt.

Did we make any progress on that shape customization stuff?
