ANDROID: vendor_hooks: Add hooks for pcp related optimization.

We want to make some optimizations to the pcp buffer. First, when directly recycling, we skip drain_all_pages when it is known that the pcp buffer is small to reduce zone->lock contention. In addition, the default pcp buffer size is still relatively small for mobile phones with large memory. We want to increase the pcp buffer area to reduce zone->lock contention.
