This reverts commit 0b216f7a.

This adjusts some of the names in the PlatformMenuBar to be more consistent with the rest of the API.

Matching engine PR is flutter/engine#32433

I noticed that AnimatedModalBarrier didn't have the onDismiss callback that ModalBarrier does, and so I added that, and while I was at it, I updated the unit tests to perform all of the tests that are done on ModalBarrier also on AnimatedModalBarrier. The tests are unchanged, other than using AnimatedModalBarrier instead.
