Add hooks to support oem's binder feature of improving binder_thread->task sched priority
1) Check if it is a specific task in trace_android_vh_binder_transaction_buffer() and store the flag to t->android_vendor_data1
2) If it is a specific binder task and binder_thread selected, raise the sched priority of binder_thread->task in runqueue.
3) If it is a specific binder task but no binder_thread selected (e.g pending_async or no free threads), insert t->work to the appropriate position in the list.
4) Reset the sched priority when BR_TRANSACTION or BC_FREE_BUFFER.
Some high-priority async binder task reset the sched priority when BC_FREE_BUFFER in trace_android_vh_binder_free_buf().
Some middle-priority async binder task reset the sched priority when driver return server "BR_TRANSACTION" in trace_android_vh_binder_transaction_received().
