vo_gpu: attempt to avoid UBOs for dynamic variables
This makes the radeon driver shut up about frequently updating
STATIC_DRAW UBOs (--opengl-debug), and also reduces the amount of
synchronization necessary for vulkan uniform buffers.
Also add some extra debugging/tracing code paths. I went with a
flags-based approach in case we ever want to extend this.
