new package: intel-mpi-benchmarks (#15745)

* Add initial attempt at intel-mpi-benchmarks package

* Add more checksummed versions

* Changes to how makefile is handled

* First working install version. Needs tuning to support building specific benchmarks

* Add variant for building specific benchmarks rather than all of them

* Minor syntax change
