Add language picker to post form

Essem requested to merge esm/firefish:language into develop

What does this PR do? Continuation of !10602 (merged) and !10603 (merged), fixes #9692. This adds a language picker to the compose form UI that allows users to specify the language a post is in. The "Auto detect" option uses tinyld to detect the post language, much like the current behavior.


This is currently a draft because while this works and can be used, there's still a few more things that can be done to improve it. Here's a checklist of what I can think of at the moment:

  • Add search to the language picker dropdown
  • Reduce height of dropdown
  • Audit the revised langmap
  • Unify/use langmap in more places

More testing is also needed to make sure this doesn't break things.
