kitty: Switch to kitty terminal emulator

Finally made the switch from alacritty to kitty. I have been thinking
about this for a while. Both, fundamentally, serve my purposes just
fine. Both are fast, customizable, gpu accelerated, and so on.
Kitty feels a little faster on the input, but this should not provide
major differences.

One big difference, however, is now very apparent and I can feel it:
Alacritty, on wayland, does not support any picture preview. It does not
support sixel, and things like w3mimg or ueberzug are based on and
require X11 to run.
Kitty brings its own graphics display library and it seems both pretty
stable and fast.
I have not done much more with it than use it in things like vifm image
previews but it should be much more stable than things like ueberzug,
much faster than things like sixel. Time will tell.

Switched other modules to make use of kitty instead of alacritty:
vifm uses kitty previews,
river spawns kitty instances,
systemd units use kitty instances,
waybar presents extra mouse-click interactions through kitty,
and styler contains a processor to style kitty permanently.

I would love to converge this all a bit more on the `$TERMINAL` env var,
but this is unfortunately difficult for things like systemd and waybar.
For waybar I currently see no real way except for a custom
`ideal-terminal` script which just goes down the list of terminal
emulators I want to run, depending on which is installed,
since it does not read env vars,
while for systemd it might be feasible to import user environment
variables,
but also connected to additional complexity and overhead which it does
not seem worth for the currently two simple service units it affects.

Also removed some obsolete sxhkd and sh settings from the move to
wayland.
