ANDROID: vendor_hooks: add hooks for f2fs issue checkpoint
Add hooks to solve the priority inversion. while the key thread needs
to update fs data, it should wake and wait for f2fs checkpoint thread
to complete the work. So one scheme is needed to ensure the priority
of checkpoint thread especially in CPU high load scenarios.
