Austin Eng 51db53fa06 dawn_wire: Harden deserialization routines
- Encapsulate deserialize buffer and size into a DeserializeBuffer
   class. This limits the possible operations so we can be sure
   buffer/size are not manually mutated such that we consume more
   bytes than available.

 - Ensure that memberLength (on deserialization) doesn't narrow (or
   widen). Previously, values were always implicitly cast to size_t.

 - Slight optimization that removes "= nullptr" initialization for
   pointers written by DeserializeBuffer::Read. These
   are always written to on success, so we don't need to initialize
   to nullptr.

Austin Eng cef68bc8b7 dawn_wire: Fix a bug with multiple injected devices
Device child objects were storing an *unstable* pointer to device
specific tracking information. Fix this by moving the tracking
information to a stable heap allocation.

Austin Eng 8bcde8e394 dawn_wire: Add Reserve/InjectDevice
Now that the wire does enough tracking to prevent a malicious client
from freeing a device before its child objects, and the device is no
longer a "special" object with regard to reference/release, it is
safe to support multiple devices on the wire. The simplest way to
use this in WebGPU (to fix createReadyRenderPipeline validation)
is to add a reserve/inject device API similar to the one we use for
swapchain textures.

Austin Eng 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.

Austin Eng a7bb5a5b74 Remove the hardcoded device tick in Server::HandleCommands
This was here to ensure all callbacks return, but this can now
be done by calling device.Tick - which Chromium does
periodically. Remove it now, especially since it will be incorrect
when the wire supports more than one device.

Austin Eng 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.

Corentin Wallez 540ababb6b Introduce a "callback" type in dawn.json
This replaces all instances of "natively defined" with callbacks and
adds information about the callbacks arguments so that their typedefs
can be autogenerated in dawn.json.

Also adds all the methods using callbacks to the list of handwritten
client commands so that the wire templates don't try to generate code
for them.

Corentin Wallez 96496828a0 Split the libdawn target in components with a single purpose.
The functionality of the dawn_headers and libdawn targets are split into
the following targets:

 - dawn_headers: the new version only exposes the "dawn.h" C API and no
   longer includes the C++ API.
 - dawncpp: the header and implementation of the C++ API that wraps the
   C API. This is unbundled from the rest so the C++ API can be used
   with libdawn_proc or other libraries implementing the C API.
 - libdawn_proc: A DawnProcTable-backend implementation of the C API.

This is needed because in follow-up commit there will be three libraries
implementing the C API: libdawn_proc that trampolines where we want, and
libdawn_native/wire that don't have trampolines for better perf.
