wl_eglstream_controller implementation for NVIDIA
This adds a new client buffer integration: wayland-eglstream-controller,
which contains the EGLStream logic from wayland-egl, and additionally
uses NVIDIA's wayland-eglstream-controller protocol to avoid the issue
where the stream is not ready at the time of first buffer attach.
This is not enabled by default. Can be used like this:
QT_WAYLAND_CLIENT_BUFFER_INTEGRATION=wayland-eglstream-controller ./pure-qml
Fixes: QTBUG-71697
Change-Id: I73bb2a8fe9852afe1b5807cbb8c35dc4c7624dad
