Add OpenCL SDK and clMath ports (#2837)

* initial clFFT porting

* OpenCL SDK half baked

* Tried fixing Debug/Release

* Remove DLL deployment

* OpenCL SDK installs

* clFFT installs

* clFFT properly depends on OpenCL

* OpenCL SDK fixes and clFFT patches

* [clfft][opencl] Simplification, use patches instead of full files.
