xwayland: Add preferred GLVND vendor to xwl_screen 

If Xwayland's EGLstream backend supports hardware acceleration with the
NVIDIA closed-source driver, the GLX library also needs to be one
shipped by NVIDIA, that's what GLVND is for.

Add a new member to the xwl_screen that the backend can optionally set
to the preferred GLVND vendor to use.

If not set, "mesa" is assumed.
