Use SysUI/Shell's transaction apply token in Launcher

Browse Source 
Launcher and SysUI/Shell have a lot of interactions
that require careful synchronization and ordering (at-least
with shell-transitions). As a result, they need to share
the same apply token or else some operations can end up
out-of-order despite being applied in-order.

Bug: 242193885
Test: Open an app, quickswitch repeatedly.
