When switching users and attempting to lock the device, the sysui main
thread becomes overwhelmed with events, creating a significant lag
between the time a message is posted and processed on the main
thread. This can be dangerous when these events are critical for
security, such as calls coming from PhoneWindowManager#lockNow() that
call KeyguardViewMediator#doKeyguardTimeout(). On older devices with
slower CPUs and less memory, the delay in processing can be
significant (15 - 30s).
The result of not prioritizing these events leads to a window of time
where a guest user can switch back to the owner, and gain access to
the owner's homescreen without needing to unlock the device with the
owner's credentials.
As a mitigation, prioritize two events originating in two specific
methods to make sure the device locks as soon as possible as well as
have the system server preemptively update its local cache.

DO NOT MERGE: Revert "Map TYPE_TRUSTED_APPLICATION_OVERLAY to system window type for A11y"
Add mechanism for a task's windows to be trusted overlays
Change InputWindowInfo::isTrustedOverlay() to be permission and flag based
These decorations set flag_slippery, to cover the unlikely event of user
tapping a screen decor and then not able to send this touch gesture to
the neighboring window.

migrateExtraStreamToClipData() will only offer to promote Uri values
if a ClipData isn't already defined, so we ensure that a ClipData
value is always defined. This blocks later promotion and granting.
