Create ring buffer for managing D3D uniforms.

* Adds a base class for the ring buffer (to be used by Metal as well),
  which tracks the current available space. APIs will need to
  implement creation of the buffer in the subclass.
* The API implementation will need to store SubmitData on command buffer
  submit, and then pass it to finishSubmit when the command buffer
  finishes.
