Subject: desktop-wayland: Patch gui-wm/hikari to use high refresh rates

hikari by default does not pick the highest refresh rate for any given
display, instead falling back to the first mode it finds. This patch
adds rudimentary support for finding the highest supported refresh rate
for the preferred resolution.

+Subject: [PATCH] Pick highest refresh rate for preferred resolution
+
+When configuring an output, hikari uses the first mode it finds. This
+means that we may not end up with the highest refresh rate for a given
+resolution. Since we usually want to make use of higher refresh rates,
+find the monitor's preferred resolution and pick a corresponding mode
+with the highest refresh rate.
