ANDROID: vendor_hooks: Add hooks for waking up and exiting control

Add hooks at process waking up and exiting routines so that oems
can control these procedures. One possible benifit is the peak of
system load can be shaved and load can be more smooth when a large
number of threads is killed once upon a time, while a sudden peak
of system load can probably lead to user junk issues.
