replace CSXformSteps::Required() in SkShader

This call is working perfectly fine as far as I reckon, but it's subtly
error-prone to not explicitly mention the alpha types when making this
kind of decision.  It just so happens that Requires() used premul/premul
just as we do here, so this should be a no-op.
