[graphics/krita] libs/ui: Remove checks for compatible styles

Git commit 650e049ee9a7f41afb4df7441fcea241addcc22d by Dmitry Kazakov, on behalf of Halla Rempt.
Committed on 17/07/2026 at 11:35.
Pushed by dkazakov into branch 'master'.

Remove checks for compatible styles

This is only relevant for distribution linux builds: users can
now select all installed styles whether they are funtional or not.

Our own builds (windows, macos, appimage) come with just our selected
set of styles (fusion, macintosh) and new styles cannot be added
to these builds.

On Android, there is no style menu.
