Handle OOM buffer allocations better This CL checks buffer sizes before creating map read/write handles. It is an error to map a buffer that can't be addressed on the CPU. It also changes client-side synchronous errors on mapAsync to be normal map failures, and not device lost errors. These should be recoverable. The CL adds additional testing for really large, but not UINT64_MAX buffers, and fixes a VVL warning when buffer allocations exceed the size of their memory heap.

Dawn is an open-source and cross-platform implementation of the work-in-progress WebGPU standard. More precisely it implements
webgpu.h that is a one-to-one mapping with the WebGPU IDL. Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.
Dawn provides several WebGPU building blocks:
