Implement key repeat for pressed key bindings

Each sway_keyboard is provided with a wayland timer event source.
When a valid keypress binding has been found, a callback to
handle_keyboard_repeat is set. Any key event will either clear
the callback or (if the new key event is a valid keypress binding)
delay the callback again.
