Add support for bitmap cursors

So far QtWayland did not support custom bitmap/pixmap QCursors.
This change adds support for them by creating a QWaylandShmBuffer and
copying the pixmap data into that buffer. The internal API to set
cursors images is changed to not only rely on wl_cursor_image, but also
allow to just set the buffer with a specific size and a hot spot.

The created WaylandShmBuffer is passed around as a shared pointer, so
that it can be automatically cleaned up once the cursor image is no
longer used on any seat.
