kwayland: Add version 5.61.0

KWayland provides two libraries:

- KWayland::Client
- KWayland::Server

As the names suggest they implement a Client respectively a Server API for the \ 
Wayland
protocol. The API is Qt-styled removing the needs to interact with a for a Qt \ 
developer
uncomfortable low-level C-API. For example the callback mechanism from the \ 
Wayland API
is replaced by signals; data types are adjusted to be what a Qt developer \ 
expects, e.g.
two arguments of int are represented by a QPoint or a QSize.
