Added vendor hook to consider ufs host/device perf heuristic
according to different platform/design

Vendor/Platform can take necessary action according to their
design/implementation

Added vendor hook before calling UFS command ops
   - trace_android_vh_ufs_perf_huristic_ctrl
Added vendor hook after sending UFS command to host
   - trace_android_vh_ufs_send_command_post_change
Added vendor hook for abort success case
   - trace_android_vh_ufs_abort_success_ctrl
