Ben Clayton c56868420d Migrate all tests over to using Default Struct Layout
The WGSL spec has been updated with 'Default Struct Layouts':
https://github.com/gpuweb/gpuweb/pull/1447

This removes the `[[offset(n)]]` decoration, and replaces it with two optional decorations: `[[size(n)]]` and `[[align(n)]]`, and a sensible set of sizes and alignments for each type.

Most `[[stride(n)]]` decorations have also been removed from arrays.

Yan, Shaobo 421584173c Fix dynamic buffer offset issues on D3D12 backend
This patch fixes
1. Inherit dynamic buffer offsets : dawn chooses vulkan
like inherit behaviour, so dynamic offsets need to be inherited.
This patch adds inherit dynamic offsets between pipelines support and
adds tests to cover it.

2. Dynamic offsets are skipped when groups have been set : in D3D12
backend, when invoke SetBindGroup, dawn will check whether this group
has already been set and skip updating root signature if the answer is
yes. However, this behaviour will affect dynamic offsets update. With
the latest patch, we always update dynamic offsets, even if they didn't
change and adds tests to cover it.

This patch also hit a dawn's issue about storage buffer validation in compute pass.
Currently the validation is a workaround to avoid access conflicts but will impact
using dynamic buffer offset in compute pipeline. Fix this issue is hard so disable

Yan, Shaobo 351ea23830 Dynamic Buffer Offset : D3D Backend
In a typical graphics application it is a common usage to update some uniforms once per draw,
and such uniforms include the word positions, orientations, and so on. In the current state of
WebGPU, this means that for each draw call we have to create a new bind group to set the right
uniform values. Bind group creation is expected to be more expensive than
recording draws because a memory allocation is required.

The functionality of dynamic buffer offset is to reduce the number of bind groups that need to
be created.

The patch implements dynamic buffer offset on D3D backend using root descriptor.

1. 'fragmentStoresAndAtomics' feature is not enabled when we create the Vulkan device.
2. The binding value of dynamic buffer offset end2end test not set correctly.

For failure reason 1, this patch enabled fragmentStoresAndAtomics.
For failure reason 2, this patch modify dawn validation logic in SetBindGroup to check

Yan, Shaobo 3dd6153eb7 Dynamic Buffer Offset : Vulkan Backend
In a typical application, most draws will use different uniforms values for
things like the world position and orientation. In the current state of WebGPU
this means that a new bind group needs to be created for each draw to set the
right uniforms. Bind group creation is expected to be more expensive than
recording draws because they incur an allocation.

This feature is to reduce the number of bind groups that need to be
created.

The patch implements dynamic buffer offset on vulkan backend. But Vulkan
takes dynamic offset as uint32_t type, which is not the same size as the VkDeviceSize
used to create buffers so we cast them for now.
