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.

The patch implements dynamic buffer offset on OpenGL backend using glBindBufferRange and adds
validation to check whether visibility of resources are none.

Corentin Wallez 2a1d8c2b1d Remove ShaderStage that doesn't exist in WebGPU.
Instead it is replaced by one enum in dawn_native and another in utils.

Yan, Shaobo f697fe3b7d Add dynamic attribute in bind group layout binding
WebGPU remove dynamic-uniform-buffer and dynamic-storage-buffer but add a new attribute in
BindgroupLayoutBinding to record whether a buffer resource is dynamic.
Dawn need to align with this change.

Yan, Shaobo 3789858479 Fix the failures in dynamic buffer offset tests with Vulkan validation layer enabled.
The root causes of these failures are as follows:
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
binding size and update binding size in dynamic buffer offset end2end test.

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.
