Some fixes to shell transitions lifecycle handling

Added a remote transitionfilter for container ordering. This way
launcher animation won't engage if it is appearing behind a
translucent task.

Modify commitVisibility to properly update client visibility
when shell transitions are enabled.

Fixed issue where activity start was deferring sync-engine
readiness even for "delivered-to-top" or cancelled activity
starts. This meant it would wait forever.

Hooked up the "enter animation complete" reporting to shell
transitions.

Removed interference by legacy freeform/maximize animation
logic (which was calling setReady at incorrect times).
