GPU: minor changes to support standalone GHOST builds

- Move gpuPush/Pop from GPU_draw.h into GPU_state.h
  as this is for pushing/popping state.
- Add 'GPU_STANDALONE' define, to bypass use of user-preferences
  for theme colors and pixelsize, as well as pbvh init/free functions.

Needed to get GHOST tests working again.
