This CL adds support for chunking large commands by first serializing large commands first into a separate buffer, and then sending the buffer data chunk by chunk. This code path is used for large writeBuffer and writeTexture, as well as the inline memory transfer service for buffer mapping. The transfer for writeBuffer and writeTexture will be optimized further in Chrome, and the inline memory transfer service is currently used only in tests. Bug: chromium:1123861, chromium:951558 Change-Id: I02491a44e653e2383174958d9c3d4a4db6fd7bde Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/28882 Commit-Queue: Austin Eng <enga@chromium.org> Reviewed-by: Stephen White <senorblanco@chromium.org>
