Instead of having its own evdev input device processing implementation,
make clutter's evdev backend use libinput to do input device processing
for it.
Two GObject parameters of ClutterInputDeviceEvdev (sysfs-path and
device-path) are removed as they are not used any more.
Before ClutterDeviceManagerEvdev had one virtual core keyboard and one
virtual core pointer device. These are now instead separated into seats,
which all have one virtual core keyboard and pointer device respectively.
The 'global' core keyboard and pointer device are the core keyboard and
pointer device of the first seat that is created.
A ClutterInputDeviceEvdev can, as before, both represent a real physical
device or a virtual device, but is now instead created either via
_clutter_input_device_evdev_new() for real devices, and
_clutter_input_device_new_virtual() for virtual devices.
XKB state and button state is moved to the seat structure and is thus
separated per seat. Seats are not a concept exposed outside of clutter's
evdev backend.

Hardware keycodes in Clutter events are x11 keycodes, which are
the same as evdev + 8, but we need to reverse the translation when
explicitly asked for an evdev keycode.

This adds a virtual function to ClutterInputDevice to translate a
keycode from the hardware_keycode member of ClutterKeyEvent to an
evdev keycode. The function can fail so that input backends that don't
have a sensible way to translate to evdev keycodes can return FALSE.
There are implementations for evdev, wayland and X. The X
implementation assumes that the X server is using an evdev driver in
which case the hardware keycodes are the evdev codes plus 8.

This backend is a event backend that can be enabled for EGL (for now).
It uses udev (gudev) to query input devices on a linux system, listens to
keyboard events from input devices and xkbcommon to translate raw key
codes into key keysyms.
This commit only supports key events, more to follow.
