ANDROID: vendor_hooks: vendor hooks for optimizing the blocking problem

caused by rwsem lock contention of reverse mapping during memory
recycling.

Dear Sir， We want to apply the following five trace hook:
1、trace_android_vh_do_folio_trylock()
2、trace_android_vh_get_folio_trylock_result()
3、trace_android_vh_folio_trylock_clear()
4、trace_android_vh_folio_trylock_set()
5、trace_android_vh_handle_trylock_failed_folio().

The optimization objectives are as follows: In the process of memory
recycling,reverse mapping is indispensable. The role of reverse mapping
is to find all vma or page tables mapped to this page through physical
address or page structure. Therefore,the process of reverse mapping will
inevitably bring synchronous operations. Whether it is file page or an
anonymous page,the synchronization operation is realized through the
rwsem read-write lock. Therefore,when kswapd or the user's key thread
enters direct_reclaim,the rwsem lock will cause the entire recycling
link to be blocked,resulting in low memory recycling efficiency and
affecting the user experience. On Xiaomi mobile phones,there is a
situation in which the reverse mapping is stuck in the rwsem read-write
lock during the file page recycling process,causing the entire recycling link to be blocked,so that the memory cannot be recycled in time. The display on the trace shows that there are a large number of D states,and its block function is rmap_walk_file,therefore,for non-forced
recycling scenarios,try_lock and asynchronous recycling are used to
handle related blocked pages.
