When performing memory reclaim, support treating anonymous and
file backed pages equally. Swapping anonymous pages out to memory
can be efficient enough to justify treating anonymous and file backed
pages equally.
Create a vendor hook inside of get_scan_count so that equal reclaim of
anon and file pages can be enabled inside of the trace hook based on
certain conditions.

Some shrinker add lock in count_objects() may cause lock contention
issues and lead all task stall on slab shrink. Add vendor hook in
do_shrink_slab() for shrinker->count_objects() latency measuring.
Add 3 oem data in shrink_control struct. Two is for
shrinker->count_objects() and shrinker->scan_objects() latency
measuring, other one to store priority, some shrinker know the reclaimer
priority can control the memory reclaim more better.
