As promosed in #1140, here are some type-coverage improvements, most of which involves the theme.__init__ parameters.

I added a script in tools that I've used to generate these param annotations. Unfortunately it's not a complete solution, because it required fixing a couple of annotations afterwards, and I also deduped a lot of duplication in the annotations using type aliases.

In order to avoid a Pyright error, I had to annotate a param in _utils/yippie.py (Pyright would otherwise infer position as str, which isn't assignable to the plot_tag_position literal).

This increases public type coverage (measured with uvx pyrefly coverage check --public-only plotnine) from 58.84% to 64.95% (+6.11%). See https://jorenham.github.io/typestats/dashboard/report/#plotnine for a fancy type-coverage dashboard.

FYI; I'm planning on opening some other type-coverage PRs like this one soon, and I was thinking of doing themes.themeable next :)
