egl: forward declare wl_resource for compatibility

Browse source 
Depending on what version of Mesa you have then eglQueryWaylandBuffer
may take a wl_buffer or wl_resource argument and the EGL header will
only forward declare the corresponding type.

The use of wl_buffer has been deprecated and so internally we assume
that eglQueryWaylandBuffer takes a wl_resource but for compatibility we
forward declare wl_resource in case we are building with EGL headers
that still use wl_buffer.
