Reland "Remove GrDeviceSpaceTextureDecalFragmentProcessor."

This is a reland of af5f9f008de060a91d8069c876a765f11c3d36f6

This was reverted due to Metal GMs failing. That is a bug in Metal where
pipeline creation fails with "internal error". Reporting to Apple, filing
Skia bug, and moving on.

Original change's description:
> Remove GrDeviceSpaceTextureDecalFragmentProcessor.
>
> It was used to sample clip masks using device coords.
>
> Replace with a more generic GrDeviceSpaceEffect that simply calls a
> child FP with sk_FragCoord.
>
> Also fix issue in GrQuadPerEdgeAA GP. It wouldn't setup coord transforms
> at all if they are all applied in the FS (explicit coords). Moreover,
> the GrGLSLGeometryProcessor::emitTransforms() helper required a valid VS
> var for local coords even when all FPs use explicit coords and wouldn't
> use a local coords var.
>
> Make CPP SkSL code gen for clone copy the explicit coord status of
> children.
