x11-libs/gtk+: add patchset for GtkSwitch unicode glyphs fallback
.. and some more patches from current upstream gtk-3-24 branch.
Tries to avoid fallback glyphs on GtkSwitch harder by using different
unicode glyphs when the best ones aren't available in any of the
installed fonts (so the hex fallback would be shown).
Tweaks long text comboboxes to behave better on wayland.
Other changes should be without much consequence to us.
