Prepare: openPMD-api 0.15.0-dev (#29484)

Anticipate openPMD-api changes in the next major release that are
already in `dev` (aka Spack `develop`):
- C++17 requirement
- drop: `mpark-variant` public dependency
- add: `toml11` private dependency

Also add @franzpoeschel as co-maintainer for the Spack package.
