Feature: Migrate OSK

[trigg]

A very augmented wf-osk from wf-osk

• Updated to gtk4mm
• Choice of ANSI or ISO approximation layouts
• Implemented autocomplete autocorrect (badly)
• • One requires a Llama file and frankly produced awful results
• • The other requires enchant-2 and aspell-en etc for language. Also bad reults.
• Added a handful of keyboard layours
• • For layouts using scancodes the keycap and keypress will match users language and no language must be hardcoded into them
• • For buttons or labels with a hardcoded label, they are considered macros and will insert unicode-letter by unicode-letter. These won't update when users layout/language is changed
• Numpad layout for numbers & pinpad entries
• • Known bug that numlock is typically set wrong and this shows up as 8-way arrow keys
• Hook into IPC to ascertain the users language changes in WF
• Options!
• • Activate causes popup (bool)
• • Deactivate causes popdown (bool)
• • Hide on start (bool)
• • Exclusion zone (bool)
• • Shape (string) the default layout when the user is typing alphabetically
• • Suggest engine (string)
• • Llama file (string) full path to a Llama GGUF file
• • Emoji size (int) font size of the emoji in the emoji picker

This is a feature, so slated for merge AFTER the feature freeze
