Vulkan: Reduce mGarbageMutex lock contention Right now mGarbageMutex is used to control access to mSharedGarbage, mPendingSubmissionGarbage, mSuballocationGarbage, mPendingSubmissionSuballocationGarbage and mOrphanedBufferBlocks. Some times garbage clean up does take a bit longer time, especially on some VM platforms. This some times causes lock contention between main render thread and background garbage clean up thread, which defeats the benefit of having garbage clean up in the background thread. This CL utilizes angle::FixedQueue for garbage list so that enqueue and dequeue can be concurrent, which avoids this lock contention.
