5ad5557667 Remove special-casing of device reference/release in the wire
The wire's device is externally owned so reference/release were no-ops.
To unify the code paths, remove the special casing and instead
take an extra ref on the device the wire server is created with. This
is functionally equivalent and will allow both the current wire code,
and the incoming change to allow multiple device/adapter creation to
both work.

This CL also makes it possible for the client to destroy the device
before child objects.
A follow-up CL will mitigate this on the server side.

f0d7cc4f5a dawn_wire: Make all objects owned by the client
This removes the logic where the Client owns the Device and the
Device owns all other objects. Ownership should be tracked in
dawn_native either with refcounting or validation to disallow
operations after an object's parent has been destroyed.

This simplifies the wire client code in that the client only
tracks allocated handles and does not manage parent/child lifetimes.
This is an important simplification so we can support multiple WebGPU
instances, adapters, and devices on a single wire.

3120d5ea0d Track and destroy all child objects on wire client destruction
This is needed so that:
 1. We can support multiple devices in the wire. The device will need
    to know how to destroy its child objects.
 2. The wire needs to be aware of all objects and their in-flight
    callbacks so that it can reject them if the wire is disconnnected.
    A future change will handle this.
 3. Fix leaks of objects on page teardown. When the page is torn down,
    the wire client is destroyed, and we skip calling release() for all
    objects since the object holding the proc table was also destroyed.

This is a reland of e757c012befa5b2e7288da9ab5a27bbd4da0dd06

cac0442277 dawn_wire: Support chunked commands
This CL adds support for chunking large commands by first serializing
large commands first into a separate buffer, and then sending the
buffer data chunk by chunk.

This code path is used for large writeBuffer and writeTexture, as well
as the inline memory transfer service for buffer mapping. The transfer
for writeBuffer and writeTexture will be optimized further in Chrome,
and the inline memory transfer service is currently used only in tests.

00d6215be9 dawn_wire/client: Add ToAPI and FromAPI helpers.
In the client code, we often need to translate between WGPUObject (the
API type) to Object* (the internal client type). This added a bunch of
reinterpret_casts that make the code less readable and more fragile.

This CL adds FromAPI and ToAPI helpers in the autogenerated
ApiObjects_autogen.h header, that convert between API and internal types
in a type-safe way.

409cf67207 Special-case GetDefaultQueue in the wire
Reland with a fix where commands only start being serialized by the
device after the first GetDevice() is called, not in the constructor.

This makes it so calling GetDefaultQueue always returns the same
object. It required updating various WireTests to account for the
additional wire calls.

93bea5cb50 Add WireClient::Disconnect to stop serializing commands
This prevents the client from continuing to send commands
when the wire connection has dropped. In Chromium this may
be because the connection to the GPU process is lost and the
transfer buffer may be destroyed.

This CL also adds a new helper to make testing callbacks

6a5418a760 Add MemoryTransfer interfaces to the wire
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.
