cc: Refactor OneCopyTileTaskWorkerPool.

Move the staging buffer pool related functionalities out to its own
file. To isolate the usage of |lock_| from OneCopyTileTaskWorkerPool,
the PlaybackAndCopyOnWorkerThread() is splitted into few other
functions.

  PlaybackAndCopyOnWorkerThread() {
    StagingBufferPool::AcquireStagingBuffer(); // with |lock_|
    PlaybackToStagingBuffer(); // without |lock_|
    CopyOnWorkerThread(); // without |lock_|, with context lock
    StagingBufferPool::ReleaseStagingBuffer(); // with |lock_|
  }
