  REGRESSION(282416 at main): [GTK][WPE] GPU process crashes in PlatformDisplay::shared()
https://bugs.webkit.org/show_bug.cgi?id=278451

Reviewed by Miguel Gomez.

Since 282416 at main the PlatformDisplay needs to be explicitly
initialized and the GPU process isn't supposed to use PlatformDisplay
(yet) so it doesn't initialize it (yet). But GraphicsContextGLGBM
creates a fence in prepareForDisplay() and GLFence uses PlatformDisplay.
For now we can remove the fence when GPU process is enabled since it's unused.
