Bug 1812970 - Avoid using Skia's deprecated clip ops. r=jrmuizel Skia upstream removed deprecated clip ops that could be used to replace the clipping stack and bypass clips. We shouldn't really need to do this anymore, as we can work around it just using public APIs. The only SkCanvas operation that allows us to bypass clipping is writePixels, which still allows us to implement CopySurface/putImageData. Other instances where we were using the replace op for DrawTargetWebgl layering support can just be worked around by creating a separate DrawTargetSkia pointing to the same pixel data, but on which no clipping or transforms are applied so that we can freely do drawing operations on it to the base layer pixel data regardless of any user-applied clipping.
