This PR emulates per control point inputs to patch constant functions. Without either an extension to look across SIMD lanes or a dedicated stage, the emulation must use separate invocations of the wrapped entry point to obtain the per control point values. This is provided since shaders are wanting this functionality now, but such an extension is not yet available. Entry point arguments qualified as an invocation ID are replaced by the current control point number when calling the wrapped entry point. There is no particular optimization for the case of the entry point not having such an input but the PCF still accepting ctrl pt frequency data. It'll work, but anyway makes no so much sense. The wrapped entry point must return the per control point data by value. At this time it is not supported as an output parameter.
