Making papi.spec better support RPM builds with cuda, rocm, and rocm_smi components

[wcohen]

Would like to make it easier for rpms to be built with cuda, rocm, and rocm_smi components enabled. The current WIP SRPM can be found as a fedora rawhide scratch build at https://koji.fedoraproject.org/koji/taskinfo?taskID=121528450. Because cuda and rocm support are not in the koji build system, the build does not have the cuda, rocm, rocm_smi support enabled by default. However, assuming the amd rocm and nvidia cuda are installed one can download the srpm and build it with the cuda, rocm, and rocm_smi support on RHEL9 with:

rpm -Uvh papi-7.1.0-5.fc39cuda.src.rpm
cd ~/rpmbuild/SPECS/
rpmbuild -with cuda -with rocm -with rocm_smi -ba papi.spec

The https://fedoraproject.org/wiki/SIGs/HC describes progress in getting the rocm support into Fedora Rawhide. There are some changes needed to get the srpm to build the rocm_smi component on Fedora Rawhide as the rpms names are different and PAPI_ROCMSMI_ROOT will need to be changed from the default.

Will, I'm not sure what we need to do to accommodate this effort. What needs to be changed wrt PAPI_ROCMSMI_ROOT?

For this issue the changes would be in papi.spec to have the correct dependencies and set PAPI_*_ROOT appropriately. Ideally, it would be good if someone could use the spec file in the tarball and build papi with those additional components. The comment about PAPI_ROCMSMI_ROOT is just mentioning that locations for rocm includes etc are going to change in the future at the papi.spec will need to take that into account.
