Fix an errorprone for GuardedBy warning

Moving all logic of IMMS#reportPerceptibleAsync into
Binder.withCleanCallingIdentity() runnable parameter to ensure it
can be guarded by ImfLock in the same code block.

To avoid a false alarm lint error caught in CL[1] that the
static analysis checker not be aware in runnable inner called
updateSystemUiLocked has guarded by the ImfLock
with running on the same thread outside the runnable.
