When creating a zero-sized buffer mapped, StagingBuffer creation
is skipped. This required adding a new MappedAtCreation state
since mStagingBuffer couldn't be used as a tag value for that.
Made the OpenGL backend always create non-zero-sized buffers.
Finally added tests for MapRead/WriteAsync and CreateBufferMapped
of zero-sized buffers.

The upstream WebGPU spec decided to not pursue CreateBufferMappedAsync,
and it adds some complexity to Dawn, so we remove it.

The server didn't take intercept the destroy() call which meant the
buffer could be unmapped by dawn_native without the status updated in
ServerBuffer. This caused crash when a subsequent UpdateMappedData
command was handled and tried to write into the mapped buffer.
The client needs to also track destroy() otherwise it could sent an
UpdateMappedData to a destroyed buffer which is a fatal error.
Tests are added that cover the client-server interaction for this, but
the pattern that the following is unfortunately not tested directly
against the wire server:
- CreateBufferMapped
- Destroy
- UpdateMappedData

This patch adds MemoryTransfer client/server interfaces and
uses it to implement data transfers for buffer mapping.
This patch also provides a default "inline" implementation of
the MemoryTransfer which is used if the embedder does not
provide one on initialization.
Because implementations of MemoryTransfer perform their own
serialization, a skip_serialize option is added to WireCmd records.

This requires some changes in the wire because WireCmd doesn't know the
size of void. This also adds a handwritten implementation of the Wire
commands for SetSubData that internally converts to uint8_t so that
WireCmd can generate the de/serialization.

This initial reasoning for having a u64 userdata was to be able to pack
two u32s in a single userdata but that was never used, and made a bunch
of code uglier than it should.

This removes blocks of code that were obviously builder-specific but
also removes the ObjectStorage::valid member that was used to implement
the maybe monad on the wire server side. This is no longer needed since
dawn_native handles the maybe monad internally now.
