Adds macros to annotate variables and functions used from same thread or queue.
ACCESS_ON is an alias of GUARDED_BY but should take thread-like object instead of mutex,
RUN_ON is an alias of EXCLUSIVE_LOCKS_REQUIRED to annotate function always run on same
thread/task_queue
RTC_DCHECK_RUN_ON - creates an object that allows use of annotated variables and functions, and adds a run-time DCHECK given thread/queue is current.
