Synchonization objects

Vulkan has multiple synchronization objects:
- Events, which provide synchronization between commands submitted
  to the same queue, or between the host and a queue.
- Fences, which insert a dependency from a queue to the host
- Semaphores, which insert a dependency between batches submitted
  to queues

For now, SwiftShader will treat these synchronization primitives as noop, since:
- Commands will be executed in order
- SwiftShader currently only supports 1 queue
