Corentin Wallez c6c7a42e6e Remove indirection for vertexStage
This is to match the work in progress webgpu.h header.

Also contains a fix for the wire where it wouldn't GetExtraRequiredSize
for structures that are by-value members of other structures.

Austin Eng 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.

These are the CommandEncoder, ComputePass and CommandBuffer descriptors
that contains nothing but a debug name for now but are important for

Also renames variables named "info" for RenderPassDescriptor to

Corentin Wallez e1f0d4e639 WebGPU error handling 2: CommandEncoder for samples and end2end tests
CommandEncoder is the replacement for CommandBufferBuilder. This commit
adds the dawn.json definition for it and an initial implementation that
wraps CommandBufferBuilder. This is done so that the code can be ported
to CommandEncoder gradually, otherwise the commit would be too big and
would risk many merge conflicts.

This converts all samples and end2end tests to use CommandEncoder.

Corentin Wallez 82fbccbd78 Introduce [Render|Compute]PassEncoder.
This splits off part of CommandBufferBuilder in separate
RenderPassEncoder and ComputePassEncoder objects. To match the WebGPU
IDL and factor some code, both these encoders inherit from
ProgrammablePassEncoder.

These encoders are pure frontend objects and record into the
CommandBufferBuilder command allocator objects, so no changes to the
backends were needed.

Error handling is still ew, because the "builder" mechanism we had
doesn't allow for "split builders". Nicer error handling will have to
wait on Dawn matching WebGPU.

All the tests and samples were updated to the new structure.

Fix glTFViewer by using push constants (#224)
* Works on Metal
* Not working on OpenGL (black screen; not sure why)
* Not working on Vulkan or D3D12 (push constants not implemented)

Fix glTFViewer (bind group + y-flip) (#222)
Doesn't completely fix the viewer - there is still a TODO about uniform buffers being updated incorrectly.

Corentin Wallez d8c068fb4f Remove explicit usage transition from the API and validation
This removes the following for both Buffer and Texture:
 - The builder's SetInitialUsage
 - The object's FreezeUsage and TransitionUsage methods
 - The CommandBuffer Transition<Object>Usage methods

All samples and tests are simplified as a result. This also obsoletes
the UsageValidationTest which is removed.

Some validation was dependent on "current usage" and hasn't been
reintroduced for implicit transitions yet:
 - Buffers can be used while mapped
 - Swapchain textures can be used after they have been presented.

Validation for these will involve collecting all the resources used by a
command buffer and will be done in a follow-up patch.

Fix ComputeBoids (#214)
I know there was some churn on which version of this shader was correct - but right now, this goes from broken on all 4 backends to working on all 4 backends. So this seems better.

The old code (accidentally?) uses descriptor arrays (I think), which are not trivial to support on all backends, so we won't use them for now.
