Subject: [PATCH 1/2] wayland/text-input: Use byte based offset in
delete_surrounding_text
ClutterInputFocus/GtkIMContext uses char based offset for
delete_surrounding, however, text_input_v3 uses byte based offset for
it. Currently only GTK with mutter can work correctly via text_input_v3
because they both forget to convert between char based offset and byte
based offset.
This commit fixes it in mutter by saving committed surrounding text in
MetaWaylandTextInput and converting char based offset to byte based
offset with the UTF-8 encoded surrounding text.
Fixes <https://gitlab.gnome.org/GNOME/mutter/-/issues/2146>.

Subject: [PATCH 2/2] wayland/text-input: Pass char based offset to
ClutterInputFocus
Wayland's text-input-v3 uses byte based offset for cursor and anchor of
surrounding text, but Clutter needs char based offset here. This commit
converts byte based offset to char based offset before passing them to
ClutterInputFocus.
Fixes <https://gitlab.gnome.org/GNOME/mutter/-/issues/3102>.
