ipc: describe libinput device configuration

This adds the device configurations to the ipc response for libinput
devices. Only supported configuration options for the device will be
added. This also moves `libinput_send_events` inside a new `libinput`
object that contains the rest of the configuration options. sway-ipc(7)
has been updated to reflect the changes and document the new additions.
