EmuScreen: Use CLEAR instead of DONT_CARE to help the render pass merger.

Browse source 
Should fix #18720

We need to annotate store mode properly too, in order to merge passes
that load with DONT_CARE.

The reason it's a problem that we fail to merge renderpasses is that old
Mali drivers get things in a terribly wrong state if you submit an empty
renderpass.
