Maintains a 11on12 resource cache on the external image to prevent re-creating the wrapped resource then flushing it per produced texture. To prevent unbounded growth, a basic cap is used which gets cleared. This change fixes signficant CPU time spent in the WebGPU command decoder for video import workloads and excessive memory overhead from swap chain buffers. Fixed: dawn:625 Change-Id: I72c07b02f6ab6877a9f21758650962c895933bf9 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/51421 Commit-Queue: Bryan Bernhart <bryan.bernhart@intel.com> Reviewed-by: Corentin Wallez <cwallez@chromium.org>
