Hopefully this fixes the problem when Kokkos yells at us when we configure with OpenMP but then test its header (which we were doing without -fopenmp), as well as any problems downstream from people missing -fopenmp in pkgconfig.
This gets some Kokkos updates from Rochi
This fixes --enable-werror --enable-paranoid-warnings --enable-kokkos builds for me.

This is a fraction of a commit authored by Rochi; I stripped off the m4 bits so we could just use the updated ACSM versions from the start.
With Kokkos we may have device compilers that can't handle them.
This is necessary for --enable-werror --enable-paranoid-warnings (and possibly just the former?) configurations with Ubuntu 26.4 Kokkos for me.
This looks like more of the sort of redundancy I want to get rid of, but I want to get compiling first.
I can't actually trigger this directly yet, but I needed it in MetaPhysicL for indirectly included Kokkos headers (at least for the version in Ubuntu 26.4) there.
"Should I add a layer of indirection to accomplish X" is one of the hardest questions in software, unless X is "nothing". Then it's easy.
This might become useful again depending on how we change things in the backend, but for now it's redundant with operator().
operator() setters here lets us avoid an indirection layer
If we had to support arbitrary third-party classes directly this would have been helpful, but we're writing our own shims here.
This gets them to respect $METHODS and $LIBMESH_RUN

Accidentally hit "make pull request" when I was aiming for the arrow for "convert to draft".
Anyway, @rochi00 is seeing a weird Lapack LU failure in adaptivity_ex3 when running this branch himself, but I can't reproduce it, so I want to see what CI environments think.
