st/nine: Use fast clears more often for MRTs
This enables to use fast clears in the following case: pixel shader renders to 1 RT 4 RT bound clear new pixel shader bound that renders to 4 RTs Previously the fast clear path wouldn't be hit, because when trying the fast clear path, the framebuffer state would be configured for 1 RT, instead of 4.
