debug: Enable cache flushing after every operation 

If DEBUG_FLUSH_CACHES is enabled then emit a MI_FLUSH after every
rendering operation. This is intended to 'fix' cases where we are
missing a required flush in the middle of a sequence of operations, such
as switching between 2D to 3D and render to sampler.
