Bug 1721036 - Delay buffer commits until the surface is ready,r=stransky
When the `MozContainer` surface is not yet ready in `Commit()`, we need to queue the commit. Similar to `nsWindow` and `WaylandVsyncSource` we can do so by registering via a callback via `add_initial_draw_callback()`. This required some logic changes which let to clean ups and simplifications in the whole file (I'm sorry it got so big). Differential Revision: https://phabricator.services.mozilla.com/D120429
