radeonsi: do not do two full flushes on every compute dispatch
v2: Add more CS_PARTIAL_FLUSH events.
Essentially every place with waits on finishing for pixel shaders
also has a write after read hazard with compute shaders.
Invalidating L2 waits implicitly on pixel and compute shaders,
so, we don't need a CS_PARTIAL_FLUSH for switching FBO.
v3: Add CS_PARTIAL_FLUSH events even if we already have INV_GLOBAL_L2.
According to Marek the INV_GLOBAL_L2 events don't wait for compute
shaders to finish, so wait for them explicitly.
