wip! renderer/native: start to add stream copy mode

Browse Source 
At the moment, mutter only supports using GBM for
doing GPU blits to secondary video cards.

This commit starts to sketch out using eglstreams
for doing the copy.

FIXME: in order to get memcpy fastpath we get
inverted colors and have to fix it up in the shader.

FIXME: need to move some of the globals to be in
a more structured place

Closes https://gitlab.gnome.org/GNOME/mutter/issues/205
