[robotpy] Fixup problems during stubgen (#8781)

Part of the `semiwrap` process that hasn't been ported over yet is
generating pyi stubs. It is possible to not have your semiwrap setup
correctly and "leak" native types into the generated python docstrings,
which causes the process to
[fail](https://github.com/pjreiniger/mostrobotpy/actions/runs/24618640845/job/71985311682#step:12:3652).
semiwrap also has a tool you can run, 'create-imports' that will read
the symbols from a build pybind library and automatically create and
sort the imports in the `__init__.py` file. This step is not enforced by
CI, which is why it hasn't been failing in `mostrobotpy` land.

This PR fixes the stubgen problems and runs reorganizes the imports. I
will have a follow up PR that can bring these automatically into the
build system after this lands. I'd do a fancy new `gh stack` but I can't
figure out if it works on forks.
