These workflows don't do anything alone; they have to be called from another workflow. Each builds (if necessary) their respective MPI implementation and then installs it to (or restores it from cache to) '${{ runner.workspace }}/<implementation>' for use in the calling workflow. Primarily created for #5032, but made more reusable for future workflows. Currently building is only done on Ubuntu with GCC.
