gpu: nvgpu: modify wait_pending

Browse Source 
The wait_pending HAL is now modified to simply
check the pending status of a given runlist.
The while loop is removed from this HAL.

A new function nvgpu_runlist_wait_pending_legacy() is
added that emulates the older wait_pending() HAL.

nvgpu_runlist_tick() is modified to accept a 64 bit
"preempt_grace_ns" value.

These changes prepare for upcoming control-fifo parser
changes.
