Fix eigen wheel builds

[bryanwweber]

Changes proposed in this pull request

• Fixes wheel builds in Cantera/pypi-packages by exporting the imported Eigen symbol as a project-global in the CMake config. By default, imported symbols are not shared to sibling directories; when the ext_manager introduced a dependency on Eigen3::Eigen, the symbol couldn't actually be found.
• Updates and pins a few build dependencies

AI Statement (required)

• Limited use of generative AI.
  I asked Gemma (I think?) about the CMake garbage and it answered correctly

Any idea which update here is causing the Pyodide build to fail -- the making Eigen "global" according to CMake, or one of the dependency updates? Do we just need to simultaneously bump some of the Pyodide-related build dependencies?

[bryanwweber]

I haven't been able to figure it out yet, but I also haven't tried very hard. I only got as far as reproducing the failure locally.

[bryanwweber]

I reverted the pyodide version changes in pixi.toml, but now I get a different error locally. Let's see if it's reproduced in CI.
