Further improve clear opts

- Removed the previous clear opt fix where Shaders would disallow Clear
  opts; it was hacky and the problem had to be tackled in a better way.
- Moved code merging Dirty BBoxes during Draw to IRenderTarget.cpp; that
  way the process to update the BBox can be a bit more complex without
  making RC::Draw() messier.
- Added states of BBox tracking to IRenderTarget
- BBox tracking can now be disabled temporarily until next frame. This
  is to prevent Clear opts from triggering when RTT is dirtied in a more
  complex way than just by quads, which can cause inconsistencies in
  tracking.
- Some new inconsistencies with temporary RTTs being incorrectly
  overdrawn were fixed.
