  [GTK] Implement BufferGBM::asNativeImageForTesting
https://bugs.webkit.org/show_bug.cgi?id=316608

Reviewed by Carlos Garcia Campos.

AcceleratedBackingStore::BufferGBM::asNativeImageForTesting() returned null,
unlike the other buffer types (BufferDMABuf, BufferEGLImage, BufferSHM). As a
result the backing-store snapshot used by the test runner
(AcceleratedBackingStore::bufferAsNativeImageForTesting, via
webkitWebViewBaseSnapshotForTesting) could not read back GBM-backed accelerated
content and fell back to a widget snapshot.

Implement it consistently with the other buffer types: download the GdkTexture
on GTK 4.16+, and copy the mapped cairo surface otherwise.
