Revert "Improve scissor state tracking in GrRTC"
This reverts commit 3b923a880bc0855772daffd95b5728795f515d5f.
Reason for revert: GrAppliedHardClip isn't tracking scissor state properly
Original change's description:
> Improve scissor state tracking in GrRTC
>
> At a low level, this changes GrScissorState from a rect+bool to a rect+size.
> The scissor test is considered enablebd if the rect does not fill the
> device bounds rect specified by the size. This has a number of benefits:
>
> 1. We can always access the scissor rect and know that it will be
> restricted to the render target dimensions.
> 2. It helps consolidate code that previously had to test the scissor rect
> and render target bounds separately.
> 3. The clear operations can now match the proper backing store dimensions
> of the render target.
> 4. It makes it easier to reason about scissors applying to the logical
> dimensions of the render target vs. its backing store dimensions.
>
> Originally, I was going to have the extra scissor guards for the logical
> dimensions be added in a separate CL (with the cleanup for
> attemptQuadOptimization). However, it became difficult to ensure correct
> behavior respecting the vulkan render pass bounds without applying this
> new logic at the same time.
>
> So now, with this CL, GrAppliedClips are sized to the backing store
> dimensions of the render target. GrOpsTasks also clip bounds to the
> backing store dimensions instead of the logical dimensions (which seems
> more correct since that's where the auto-clipping happens). Then when
> we convert a GrClip to a GrAppliedClip, the GrRTC automatically enforces
> the logical dimensions scissor if we have stencil settings (to ensure
> the padded pixels don't get corrupted). It also may remove the scissor
> if the draw was just a color buffer update.
