mpichversion: Adding feature string for GPU support for easy detection

[yfguo]

Pull Request Description

This PR add new feature strings to mpichversion for the GPU support. MPICH built with CUDA, HIP or ZE support will show cuda, hip or ze in the MPICH Features of mpichversion. This allow external tools to easily check for GPU support of the library.

This PR also change the configure of MPICH test suite to detect if the MPICH library passed in --with-mpi= actually have GPU support before checking the availability of corresponding GPU libraries. Previously, the configure of the test suite will check and configure for GPU support even if the MPI does not support GPU (never checked). This leads to failure on sunspot with CPU-only MPICH build. Because ZE library is always present, the test suite will be configured with ZE support while a CPU-only MPICH is provided. The benchmark will failed at runtime due to unable to load libze_loader.so.
