egl: Update to Wayland 1.2 server API

Since Wayland 1.2, struct wl_buffer and a few functions are deprecated.

References to wl_buffer are replaced with wl_resource and some getter
functions and calls to deprecated functions are replaced with the proper
new API. The latter changes are related to resource versioning.
