Add support for click assist, namely simulated secondary click (on a
long primary button press) and hover click support (simulate a click when
the pointer remains static for some time).

For accessibility features, being either keyboard accessibility to
implement mousekeys, or pointer accessibility to implement simulated
secondary click or dwell click, we need to have a virtual device.
Add that virtual device in ClutterInputDevice so it can be used either
for keyboard or pointer accessibility.

clutter_input_device_get_physical_size was just used for device mapping
heuristics in MetaInputMapper. It now started using the info from udev
on for both backends, so this means this clutter API is no longer
necessary.

On X11, when AccessX is enabled, all X11 clients benefit from the
AccessX features, including gnome-shell/mutter, meaning that special
keys like the overview or other shortcuts are also affected.
To achieve the same in Wayland, we need to implement the same features
in clutter main rather than the Wayland backend, so that all depending
code within the compositor but also Wayland clients (which rely on the
compositor to get keyboard events) similarly benefit from the
accessibility features.
Add hooks to the clutter main loop to be able to implement such
features.

Clutter discards any motion event if next event happens to also be a
motion event. This is problematic when the motion event carries
relative motion deltas, since the information about them is completely
lost.
Until we have moved away made the stage stop discarding motion events,
lets work around the issue by compressing them, effectively adding
multiple relative motion deltas together, would one be discarded.

This function call only applies to tablets, and thus will error
out unless it's called with CLUTTER_TABLET_DEVICEs. This will
allow setting absolute/relative mapping on those on the fly, as
this is optional.
This will only be practical for pads (and maybe generic buttonsets in
the future?), we just need to know the number as the events will also
contain a number as the identificator.
