direct3d: Commit viewport state before clearing, attempt 2.

Browse Source 
This reintroduces the fix from 0e16ee8330, but just marks
the viewport state as dirty after a clear that needs to expand the
viewport to fill the render target, as we'll need to also reset
the orthographic projection state elsewhere, and that won't
happen if we clear the dirty flag here.

Fixes #4210.
(again.)
(...sorry...!)
