Matthias Clasen d719a3d877 textbtree: Return tags in a GPtrArray 
One of the callers prefers that, it lets us avoid
copying the array in one place, and generally makes
for better code.

/**
* GtkTextTag:
*
* A tag that can be applied to text contained in a `GtkTextBuffer`.
*
* You may wish to begin by reading the
* [text widget conceptual overview](section-text-widget.html),
* which gives an overview of all the objects and data types
* related to the text widget and how they work together.
*
* Tags should be in the [class@Gtk.TextTagTable] for a given
* `GtkTextBuffer` before using them with that buffer.
*
* [method@Gtk.TextBuffer.create_tag] is the best way to create tags.
* See “gtk4-demo” for numerous examples.
*
* For each property of `GtkTextTag`, there is a “set” property, e.g.
* “font-set” corresponds to “font”. These “set” properties reflect
* whether a property has been set or not.
*
* They are maintained by GTK and you should not set them independently.
