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.
