Update Talon side for new destination types

[AndreasArvidsson]

Since I had to basically update every capture and action with the new formats I took the liberty of doing some general cleanup and maintenance in this pr.

Ponderings:

• Should we create a single python file with Cursorless public interface? Today I believe some of them are in actions and some in snippets and so on.
• It's quite hard to know where the default spoken forms are located. I'm leaning more and more towards just having a single folder with son files that the fine all our spoken forms.

Fixes #1440
Fixes #725
Fixes #803

Checklist

• Handled migration of csv files
• Update cheat sheet
• Update documentation
• Migrate modifiers to data classes?
• Figure out how to handle fallback of Cursorless commands when the editor is not in focus in a more standardized way
• I have added tests
• I have updated the docs and cheatsheet
• I have not broken the cheatsheet

@pokey I think this is ready for a preliminary review. There are still a few tasks left to do, but I think discussing the current direction could be useful.
I've done some rudimentary testing and everything appears to be working. My plan is to start working on the Talon grammar testing using this branch of Cursorless to get some more manual testing done.

Nice!

Re testing: you mean you'll base the testing branch off main, but will install this PR locally to drive while you're developing?

Exactly like that
