Add decorators for determining keyboard and keymap based on current directory (#8191)
* Use pathlib everywhere we can

* Improvements based on @erovia's feedback

* rework qmk compile and qmk flash to use pathlib

* style

* Remove the subcommand_name argument from find_keyboard_keymap()

* add experimental decorators

* Create decorators for finding keyboard and keymap based on current directory.

Decorators were inspired by @Erovia's brilliant work on the proof of concept.
