[gnome-builder/wip/gtk4-port] plugins/editorui: fixup formatting action

[Christian Hergert <chergert src gnome org>]

commit 3cd4ee71b4d1bcdbab0d43cf9ecda711a4c07a86
Author: Christian Hergert <chergert redhat com>

    plugins/editorui: fixup formatting action
    
     * Release formatter options object when we're done with it
     * Cleanup assertions/formatting
     * Use ide_object_warning() so the user can get a message
     * Rename some functions to avoid short functions which can clash with
       libc/stdlib type stuff.
     * No need to fetch indent-width since we don't use it currently (although
       we should probably start doing that in formatters soon).
