Currently the datepicker restores focus when the closing sequence starts, but in some cases that can cause focus to be lost. When the calendar view changes, we delay moving focus for a while in order to work around a VoiceOver issue. This means that if a closing sequence is kicked off while there's an in-progress view change, focus may end up being restored, then moved back into the calendar which then gets destroyed. This can be seen in the "Datepicker emulating a Year and month picker" example.

These changes resolve the issue by moving the focus restoration all the way to the end of the closing sequence.

Fixes #25564.

// Since we restore focus after the exit animation, we have to check that
// the user didn't move focus themselves inside the `close` handler.

I couldn't write a test for this, because there are several timeouts and animations happening at the same time and flushing one of them flushes everything.
