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.
* Use a descriptor for BindGroupLayout
* Fix MatchesLambda
* Add WireTests.StructureOfStructureArrayArgument
* Add BindGroupValidationTests.BindGroupLayoutCache
We are changing all object creation to use descriptors but there is no
creation argument to pass for queue, so instead Device::CreateQueue
takes no argument.
This as an API change to get closer to the direction in which WebGPU is
headed. The API change in next.json caused a ton of files to be changed
in the same commit to keep things compiling.
API: the Framebuffer and RenderPass objects are now merged in a single
RenderPassInfo that contains the attachments, loadOps and clear values
for a BeginRenderPass command. The concept of subpass is removed.
The RenderPass creation argument to RenderPipelines is replaced by
explicitly setting the format of attachments for RenderPipeline.
Validation: SetPipeline checks are changed to check that the attachments
info set on a RenderPipeline matches the attachments of the render pass.
Backends: Most changes are simplifications of the backends that no
longer require and indirection to query the current subpass out of the
render pass in BeginSubpass, and don't need to get the attachment info
from a RenderPass when creating RenderPipelines. In the Vulkan backend,
a VkRenderPass cache is added to reuse VkRenderPasses between
RenderPassInfos and RenderPipelines.
Tests and examples: they are updated with the simplified API. Tests
specific to the Framebuffer and RenderPass objects were removed and
validation tests for RenderPassInfo were added.
Tested by running CppHelloTriangle on all backends, end2end tests on all
platforms and all examples on the GL backend.

This fixes the issue where the default texture wasn't uploading
correctly (due to 3f47729, changes in row pitch validation) by just
removing the broken texture entirely.
GetWindow and SwapBuffers are function of Windows.h and using the same
name causes a compile error.
This commit also changes Util's GetProcTableAndDevice to CreateNXTDevice
because we might need to call NXT procs when creating the C++ device.
