gallium/radeon: add RADEON_USAGE_SYNCHRONIZED
This is really the behavior we want most of the time, but having a
SYNCHRONIZED flag instead of an UNSYNCHRONIZED one has the advantage that
OR'ing different flags together always results in stronger guarantees.
The parent BOs of sub-allocated buffers will be added unsynchronized.
