This also removes the GstWlMeta and adds a wrapper class for wl_buffer which is saved in the GstBuffer qdata instead of being a GstMeta. The motivation behind this is mainly to allow attaching wl_buffers on GstBuffers that have not been allocated inside the GstWaylandBufferPool, so that if for example an upstream element is sending us a buffer from a different pool, which however does not need to be copied to a buffer from our pool because it may be a hardware buffer (hello dmabuf!), we can create a wl_buffer directly from it and first, attach it on it so that we don't have to re-create a wl_buffer every time the same GstBuffer arrives and second, force the whole mechanism for keeping the buffer out of the pool until there is a wl_buffer::release on that foreign GstBuffer.
