CMAKE_HIP_KNOWN_FEATURES

Apparently, we have:

https://cmake.org/cmake/help/latest/prop_gbl/CMAKE_CXX_KNOWN_FEATURES.html

and

https://cmake.org/cmake/help/latest/prop_gbl/CMAKE_CUDA_KNOWN_FEATURES.html

but there is no equivalent for HIP.

Is this an oversight? It seems unfortunate to have HIP be a language in CMake but not actually have that support be full-featured, as C++ standards are something that HIP users need just as much as CUDA.

Thanks.
