[GTK][WPE] white noise images for dma_buf atlas on i915 + Intel Arc
https://bugs.webkit.org/show_bug.cgi?id=311103
Reviewed by Nikolas Zimmermann.
The combination of i915 driver and Intel Arc caused white noise for atlas image
uploading. Using xe driver work fine for the video card.
Using CPUMappingStrategy::GBMBoMap and unmapping in ~AccessScope() can work
around the issue for i915.
