Merge develop into main (#339)

- Update ILI9341 driver to v2.0.1
- Lots of code cleanup for apps
- Refactor app "type" into "category" and added flags to the manifest (for show/hide statusbar and for hidden apps)
- Rename some ElfApp-related functionality and improved the way the static data was managed
- Rename "filebrowser" to "files"
- Added cstring functions to tt_init.cpp
- Minor fix in Boot app
- Updated external apps for SDK changes
