puzzles: resync with upstream

This brings the puzzles source in sync with Simon's branch, commit fd304c5
(from March 2024), with some added Rockbox-specific compatibility changes:

https://www.franklinwei.com/git/puzzles/commit/?h=rockbox-devel&id=516830d9d76bdfe64fe5ccf2a9b59c33f5c7c078

There are quite a lot of backend changes, including a new "Mosaic" puzzle.
In addition, some new frontend changes were necessary:

- New "Preferences" menu to access the user preferences system.
- Enabled spacebar input for several games.
