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 1b31dc0bb2 Add a BufferConsumer primitive for wire [de]serialization
BufferConsumer wraps a buffer pointer and size and exposes a
limited number of operations to get data while decrementing
the remaining available size. This makes it so that code
reading or writing into a buffer cannot easily consume more
bytes than available.

This CL guards against serialization overflows using
BufferConsumer, and it implements GetPtrFromBuffer
(for deserialization) on top of BufferConsumer. A future patch
will make the rest of the deserialization code use BufferConsumer.

Austin Eng 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.

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.

This removes blocks of code that were obviously builder-specific but
also removes the ObjectStorage::valid member that was used to implement

dawn_native handles the maybe monad internally now.

Corentin Wallez d8c1a48fc4 WireCmd: require opt-in to treat ID 0 as nullptr instead of error.
In preparation for the descriptorization of BindGroup, support was added
to treat wire ID 0 as nullptr for a bunch of objects. Now that we have a
fuzzer for the wire+frontend, we need to validate when we have a 0 id.
Either the wire needs to reject the ID or the frontend needs to validate
against nullptrs. Since only few entrypoints will have a use for
nullptrs (bind groups, render pass resolve textures), we require an
opt-in in the JSON file for a structure member or an argument to be
optional.

This disables the tests related to ID 0 = nullptr, because we don't yet
have optional argument/members in dawn.json.
