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.

These additions to dawn.json don't require changes to users of the C++
API so they are done now to prepare for webgpu.h. Validation is added
that forbids using the new enum values and non-default values for
members until they are implemented.

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.

Since SPIRV-Cross outputs HLSL shaders with RWByteAddressBuffer,
we must use D3D12_BUFFER_UAV_FLAG_RAW when making the
UNORDERED_ACCESS_VIEW_DESC. Using D3D12_BUFFER_UAV_FLAG_RAW requires
that we use DXGI_FORMAT_R32_TYPELESS as the format of the view.
DXGI_FORMAT_R32_TYPELESS requires that the element size be 4
byte aligned. Since binding.size and binding.offset are in bytes,
we need to divide by 4 to obtain the element size.

This patch fixes a crash issue that on D3D12 backends Dawn will crash
when we create too many views from cbvSrvUav or sampler descriptor heaps
as both of the heaps have fixed sizes.
To fix this issue we count the number of views that are required
in these two heaps before allocating memory for them, so that the
memory allocation from these two heaps will always succeed.

If a bindgroup was re-used in multiple command buffers in a single call
to queue.Submit(), it was skipping the creation of the corresponding
descriptor heap for that bind group in the second command buffer.
The fix is to use the command buffer's index into the submit command as
part of the key for the bind group's descriptor heap.

This includes a bunch of fixes for clang warnings in Windows specific
code that was only compiled by MSVC previously. This also tidies up some
BUILD.gn issues on Windows.
