Summary

Run most tests in a single Python instance, initialized at start and shutdown at the end
Improve uv CI setup
Fix python test runner by essentially replacing it with a call to pytest.main
Improve the PythonDLL exception
Run tests that require reinitialization of the PythonEngine only on .NET Framework/Mono, where we still have a working formatter for the stashing

TODO:

Remove PythonEngine.Initialize() and .Shutdown() from all fixtures where it's not strictly necessary
Ensure that all fixtures reset the environment (e.g. by adjusting the base type providers and codecs back to the default)
Move the remaining fixtures into a separate project that runs all actual tests in individual processes (not needed, we can run those tests on Mono)
Reenable all disabled tests (all but the low-level ones)
Fix the domain reload tests (or ditch them)

Sorry, something went wrong.
