[PATCH wayland] wayland-egl: rename wl_egl_window::private to driver_private

[Emil Velikov]

From: Emil Velikov <emil.velikov at collabora.com>

private is a reserved keyword in C++. Thus if one is to have a backend
driver written in said language build will fail as below:

.../wayland-egl-backend.h:56:8: expected unqualified-id before ‘private’

Rename it to driver_private and update the test.

NOTE: version bump is not required since:
 - this is a pure API change, ABI is identical
 - hardware drivers already require [minor] changes to move to the
upstream wayland-egl-backend.h

Patch depends on the https://patchwork.freedesktop.org/series/31663/
series. One could apply it directly after 1/8 of ^^ although I kept
it separate to emphasise, "why change" and "its safe".
