Vulkan: Add FixedQueue class for CommandProcessor::mTask
This CL adds FixedQueue class. It uses std::array for the storage. It
supports concurrent push and pop from two different threads. If producer
want to push from two different threads, then proper mutex must be used
to ensure the access is serialized. Similarly if consumers want to pop
from two different threads, a mutex must be used to ensure serialized
access. Caller must ensure queue is not empty before pop and not full
before push.
This CL switches CommandProcessor::mTasks to FixedQueue and moved
mSubmissionMutex to protect the serialized submission (i.e, pop from
queue). mWorkerMutex is still used to protect push operation. With this
change, we now supports continued enqueue to mTask of CommandProcessor
while other context is doing
CommandProcessor::waitForResourceUseToBeSubmitted().
