Remove gui dependencies from alacritty_terminal

This commit removes font dependency from alacritty_terminal,
so it'll simplify the usage of alacritty_terminal as a library,
since you won't link to system's libraries anymore. It also
moves many alacritty related config options from it.

Fixes #3393.
