  [WPE] WPE Platform: use the primary device to allocate buffers when doing direct scanout under wayland
https://bugs.webkit.org/show_bug.cgi?id=268821

Reviewed by Nikolas Zimmermann.

We currently use always the render node, but for scanout we should use
the primary device. GBMDevice has now two devices, render and display,
and only the filename is set during the initialization. We search the
DRM node for the given file and set the filename of the render and
display devices. If they are the same display is not initialized and
render is always used. When the GBM device is requested for the first
time, the device is actually opened and GBM device created, to make sure
we only create the devices if they are really used.
