[ozone/wayland] Use SurfacelessEGL when supported

Use SurfacelessEGL for ozone/wayland, when supported

Since [1], chrome --mash --ozone-platform=wayland fails to
launch in some systems, where the call to
PbufferGLSurfaceEGL::Initialize (ui/gl/gl_surface_egl.cc) fails
at

  EGLSurface new_surface =
      eglCreatePbufferSurface(display, GetConfig(), &pbuffer_attribs[0]);

... because GetConfig does not return a valid EGLConfig instance.

As per @kylechar's advice, this CL opt-in for a SufacelessEGL
creation, if supported, rather than PbufferGLSurfaceEGL, similarly
to how it was prior to [1].
