During StartUp/ShutDown(), if another running task in message loop needs
api_lock, then it will deadlock. Release api_lock in StartUp and
ShutDown when current thread is blocked by another task
Bug: 116081383
Test: run unit test

* Add a private method MessageLoopThread.DoInThreadDelayed to post a
delayed task in message loop, as an alternative approach to osi alarm
clock
* Add a unit test for MessageLoopThread to check ShutDown() waits until
current task finishes
* Add Timer using MessageLoopThread.DoInThreadDelayed
* Timer provides similar API as osi alarm, and uses same OS clock (boot
timer) as alarm
* Add benchmark and unit tests to ensure the performance is comparable
to the existing osi alarm
Test: Run unit test and benchmark test
./test/run_unit_tests.sh bluetooth_test_common
./test/run_benchmarks.sh bluetooth_benchmark_timer_performance
--benchmark_repetitions=10 --benchmark_report_aggregates_only=true

* Add MessageLoopThread to abstract thread implementation to our code
* Add ExecutionBarrier utility class to help with thread synchronization
* Add more performance tests and performance benchmarks to evaluate
execution efficiency in both batch and sequential usages, for various
thread implementations including:
- libosi reactor on pthread
- MessageLoop on libosi reactor on pthread
- MessageLoop on STL std::thread
- MessageLoop on Posix pthread
- MessageLoop on libchrome base::Thread
- MessageLoop on MessageLoopThread
