ADIOS2: Build for both MPICH and MPItrampoline

I'm not sure this built the right set of packages. It doesn't seem to have built separate packages for MPICH and MPItrampoline. I'm marking this as a draft. How do I correct this?

[vchuravy]

I think you also need to pass the new platform set to build_tarballs.jl you will also need to declare a dependency on MPIPreferences.jl so best to wait until that is registered.

[giordano]

This should be good to go now also with regards to MPIPreferences? Or should we fix

Yggdrasil/platforms/mpi.jl

Lines 11 to 12 in 3128588

	# FIXME: When MPIPreferences is registered both `binary` and `abi` should be const
	# and the jll packages using this tag shall depend on MPIPreferences.jl

first?

[vchuravy]

We need to either wait for JuliaRegistries/RegistryCI.jl#448, or @eschnett ping me after the merge and I will merge it manually into the Registry,

I have done all my tests on LAMMPS_jll so I think this LGTM, except that we should add OpenMPI support to avoid JuliaPackaging/JLLWrappers.jl#40 becoming a problem immediately.

[eschnett]

This might be ready now!

[giordano]

This is building also for OpenMPI, right? So that

except that we should add OpenMPI support to avoid JuliaPackaging/JLLWrappers.jl#40 becoming a problem immediately.

shouldn't be a concern anymore.

[eschnett]

Yes, I added OpenMPI support. The respective tests failed initially, so I assume it's properly tested.

[giordano]

@vchuravy any objections against merging this now? If not, I'll merge this tomorrow
