Reland "Vulkan: Use specialization constant for halfRenderAreaWidth" This reverts commit b1917fe1a314709cd9f7f53b2923d6be0e8bbf6c. Reason for revert: Not the root cause. See bug. Original change's description: > Revert "Vulkan: Use specialization constant for halfRenderAreaWidth" > > This reverts commit ff38106d62fca2e36ec2db1cd580b546fd53ae43. > > Reason for revert: Speculative revert to clear up AMD. See bug. > > Bug: chromium:1154356 > > Original change's description: > > Vulkan: Use specialization constant for halfRenderAreaWidth > > > > halfRenderArea is used by fragment shader to adjust gl_FragCoord for > > rotation and yflip compensation.
