iris: Skip double-disabling TCS/TES/GS after BLORP operations
BLORP always turns off TCS/TES/GS. If regular drawing also has them
disabled (the overwhelmingly common case), then leaving them disabled
is just fine by us and we can skip dirtying them, as that would just
re-disable them a second time on the next draw.
If they are actually enabled, however, we do need to flag them.
Cuts 52% of the 3DSTATE_HS packets in an Aztec Ruins trace.
