dawn_native: Use correct integer width for SetSubData.

SetSubData's count is a uint64_t while Queue::WriteBuffer's is a size_t
so we add a small validation check that no narrowing will occur.

No test is added because SetSubData will be removed soon, and it will be
hard to test because of the Null backend's artificial OOM.

This was found while debugging an unrelated fuzzer issue.
