Log Message:
-----------
[GTK] imported/w3c/web-platform-tests/webrtc-stats/outbound-rtp.https.html is
crashing in a Skia codepath
https://bugs.webkit.org/show_bug.cgi?id=304134
Reviewed by Adrian Perez de Castro.
When using Skia with GPU acceleration, NativeImages backed by textures must be
destroyed on the same thread where the Skia GrDirectContext was created, not on
the compositor thread. Releasing GPU resources on the wrong thread corrupts
Skia's GrResourceCache, leading to bounds check failures and crashes.
This patch ensures that in ~CoordinatedPlatformLayerBufferNativeImage(), if the
image is texture-backed, its destruction is dispatched to the main thread.
This also fixes crashes/assertions in:
