Wire: Make validation error prior to OOM if mappedAtCreation == false

This patch updates the validations about CreateBuffer() with dawn_wire
to match the latest WebGPU SPEC.

According to the SPEC, the validations in CreateBuffer() should be
executed in the below order:
1. If mappedAtCreation == true, return nullptr and a RangeError will be
   generated in Chromium.
2. Validate BufferDescriptor and check if there is OOM at device timeline
3. Check if there is OOM at content timeline
