[dawn] Reduce max buffer size on NVIDIA to 2GB There has been an observation that on vulkan if one specifies a buffer size greater than 2GB one might see OpArrayLength report '0'. Rather than have these critical errors in the wild we simply reduce the max buffer size for now. We may revisit in the near future. It was also discovered that apple devices will fail this test when not using tier limits. This is a bug but it will not impact chrome.
