geopm: Add v3.1

[bgeltz]

• Add support for GEOPM v3.1 to all existing packages.
• Add py-geopmpy as it is now built/packaged separately from geopm-runtime.
• Docs have been moved to their own package and as such now build separately. The docs packaging is WIP and may arrive in a future PR.

Hi @bgeltz! I noticed that the following package(s) don't yet have maintainers:

• librsvg
• py-blosc2

Are you interested in adopting any of these package(s)? If so, simply add the following to the package class:

    maintainers("bgeltz")

If not, could you contact the developers of this package and see if they are interested? You can quickly see who has worked on a package with spack blame:

$ spack blame librsvg

Thank you for your help! Please don't add maintainers without their consent.

You don't have to be a Spack expert or package developer in order to be a "maintainer," it just gives us a list of users willing to review PRs or debug issues relating to this package. A package can have multiple maintainers; just add a list of GitHub handles of anyone who wants to volunteer.
