Suggestion: make a hip-like-graph base that can be specialised for cuda, rocm and hip?

Currently only CUDA is supported by the cudaGraph, but I wonder if a "hiplikeGraphBase" could be implemented instead that is specialised for CUDA, HIP and ROCm as to allow more GPU vendors. If it works, the current `cudaGraphBase` and `cudaGraphExecBase` could potentially be replaced with `hiplikeGraphBase</*cuda-tag or cuda-settings*/>` and `hiplikeExecBase</*cuda-tag or cuda-settings*/>`.
