Remove hip-hcc codes: Part three

1.Rename include/hip/hcc_detail/ as include/hip/amd_detail/

2.Rename include/hip/nvcc_detail/ as include/hip/nvidia_detail/

3.Create __HIP_PLATFORM_AMD__ to replace __HIP_PLATFORM_HCC__

4.Create __HIP_PLATFORM_NVIDIA__ to replace __HIP_PLATFORM_NVCC__

After hcc_detail, nvcc_detail, __HIP_PLATFORM_HCC__ and __HIP_PLATFORM_NVCC__
have been removed from upstream, they will be removed from hip runtime.
