Right now, p4est in P4est_jll.jl is compiled without MPI support:
https://github.com/JuliaPackaging/Yggdrasil/blob/999e6cf6b9054a05a4e76a1d23de93c5651396a2/P/P4est/build_tarballs.jl#L21

Let's try to fix that by compiling against MPICH_jll on Linux/MacOS/FreeBSD and MicrosoftMPI_jll on Windows.

Blocked by #5 since before we enable MPI support, we should have the ability to switch out the p4est backend provided via P4est_jll.jl against a system-installed library. Otherwise, P4est.jl will not even work on systems that switch out the MPI backend in MPI.jl, even if we are not using p4est in parallel.
