CUDA half RWTexture write support/doc improvements (#1839)
* #include an absolute path didn't work - because paths were taken to always be relative.
* Fix for writing to RWTexture with half types on CUDA.
* CUDA half functionality doc updates.

D3D12 also appears to have problems doing calculations with half. +In order for half to work in CUDA, NVRTC must be able to include `cuda_fp16.h` and related files. Please read the [CUDA target documentation](cuda-target.md) for more details. + ## u/int64_t Type Requires SM6.0 which requires DXIL for D3D12. Therefore not available with DXBC on D3D11 or D3D12. |
