  [GTK] Use EGL_MESA_image_dma_buf_export if available when GBM is disabled
https://bugs.webkit.org/show_bug.cgi?id=258193

Reviewed by Alejandro G. Castro.

We currently fall back to read pixels and shared memory when GBM is not
available, but we can actually use EGL_MESA_image_dma_buf_export
extension if available which is a lot more efficient.
