wlfreerdp: initial Wayland client

Implement an initial Wayland client, which will build if
the wayland-client development libraries are detected
(or if -DWITH_WAYLAND:BOOL=ON is set). It is currently
view-only, but inputs will be implemented soon.

It uses the software SHM interface, which means it does not
require GL acceleration to run. It should be compatible
with any compositor
