Repeatedly creating and destroying WebGPU devices in a loop causes
large amounts of memory to pile up in the GPU process. Much of this
memory comes from the D3D12 command queue.
Releasing the command queue early in DestroyImpl before the destructor
runs goes a long way towards relieving the memory pressure.

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

Pads serialized wire command buffers to 8 bytes so that we don't have
misaligned write/reads which can cause SIGILL depending on platform and
compilation mode, i.e. -c dbg in google3 builds.
- Adds helpers for aligning sizeof calls.
- Adds constant for wire padding (8u).
- Modifies BufferConsumer to allocate according to padding. This
guarantees that when we [de]serialize stuff, the padding should be
equal on both sides.
- Modifies extra byte serialization code (adding CommandExtension
struct). This makes it clearer that each extension needs to be
padded independently. Otherwise, before in wire/client/Buffer.cpp,
since the read/write handle sizes were being passed as a sum, but
read out separately from the BufferConsumer, we corrupt our pointers.
- Adds some simple unit tests.
