freedreno: support discarding previous rendering in special cases
Basically, to "DCE" blits triggered by resource shadowing, in cases
where the levels are immediately completely overwritten. For example,
mid-frame texture upload to level zero triggers shadowing and back-blits
to the remaining levels, which are immediately overwritten by
glGenerateMipmap().
