This patch is the first one of the descriptorization of render pass. In
this patch we add support of RenderPassColorAttachmentDescriptor
and RenderPassDepthStencilAttachmentDescriptor to
RenderPassDescriptorBuilder.
This patch also adds StoreOp to render pass color and depth stencil
attachment descriptor.
RenderPassDescriptorBuilder will be completely removed in the next
patch.

This patch updates the definition of TextureDescriptor to make it match
WebGPU IDL:
1. Rename 'arrayLayer' to 'arraySize'
2. Add the missing member "sampleCount" and check that currently
sampleCount can only be 1.

This commit adds utils::MakeBindGroup to make code craeting bind groups
nicer to read. Additional tests are added that give 100% coverage of
ValidateBindGroupDescriptor.

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.

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 directory used to contain both the state tracking code for the
backends, and the common utilities that could be used both by the
backends and the rest of the code. Things are now:
- src/common is utility code for the whole repo
- src/backend contains libNXT's code
- src/utils is utility code that we don't want in libNXT
This commit also changes all includes to use global paths from src/
bacause it had to touch a bunch of #include statements anyway.
