NVTRC 64 bit requirement (#1792)
* #include an absolute path didn't work - because paths were taken to always be relative.
* Made 64 bit requirement clearer for CUDA/PTX.
Added compile assert for NVRTC for 32 bit OS, that are known to require 64bit.
* Disabled location of NVRTC on linux/win x86.
* Only restrict NVRTC on windows
* Simplify checking on 64 bit windows for NVRTC.
