Move weston_output EGL state into gles2-renderer.
This introduces callbacks for output creation and destruction for the
gles2-renderer. This enables the gles2-renderer to have per-output
state. EGL surface creation is now done by the output_create callback
and the EGL surface is stored in the new per-output gles2-renderer
state. On the first output_create call, the gles2-renderer will setup
it's GL context. This is because EGL requires a EGL surface to be able
to use the GL context.
