Try to minimize the external dependencies for OMPI wrappers.

The solution put forward here consist of creating a convenience library, opal-tiny, that holds all the basic things we need to have a working app with minimal external dependencies.

More detailed discussion in #9869.

There is one point that needs to be clarified: why we need to register our output files with PMIX.

I linked this to issue #9869. Is that correct?

What's the status on this PR, are we agreed that this is the correct fix for #9869 ?

I started https://github.com/bwbarrett/ompi/tree/bugfix/mpicc-dependencies to make this a bit more clean to merge into main, but have run out of time and I'm not sure when I'll be able to come back to it. I think most of the hard problems are solved in that branch, but there's definitely some cleanup work in all the patches before it can become a PR.
