SwiftShader does not export function pointer type information.
So, when fuzzing with UBSAN, fuzzers break whenever calling
a vk* function since it thinks the type of the function pointer
does not match.
Workaround this problem by proxying through a std::function
in UBSAN builds. The std::function delegates to a Call method
which does the same cast of the function pointer type, however
the Call method is tagged with
`__attribute__((no_sanitize("function")))` to silence the error.

This patch adds the support of the experimental feature
chromium_experimental_dp4a on Vulkan. Currently this
feature is enabled on Vulkan backend only when DP4a

This change moves the bulk of the existing GPUInfo functionality into an autogenerated source built from a JSON file that describes the GPU
vendor and device IDs, with device IDs broken down by GPU architecture.
Also adds the fields needed to implement GPUAdapterInfo in Blink to the AdapterProperties.

When converting values between two concrete types, handle the case that
the value is unrepresentable by the target type.
For integers, the converted value will be either the maximum or minimum
value for the integer type.
For floats, the converted value will be positive or negative infinity.

Currently Dawn ignores all zero-attribute vertex buffer in the given
pipeline descriptor when creating RenderPipelineBase because
zero-attribute vertex buffer is treated as unused slot, however the spec
doesn't state that zero-attribute vertex buffer should be ignored.
To support zero-attribute vertex buffer, this commit has the following
changes.
1. Add VertexBufferNotUsed enum value to wgpu::VertexStepMode to
represent unused slots
2. Ignore VertexBufferNotUsed step mode buffers when creating
RenderPipelineBase and add tests to check it
3. Record zero-attribute vertex buffers when creating RenderPipelineBase
and add tests to check it
4. Fix VertexStateTest::LastAllowedVertexBuffer broken by the above
changes
Temporarily we set the enum value of
wgpu::VertexStepMode::VertexBufferNotUsed to 0 to pass the CTS tests
because currently empty vertex buffer slots step mode can be
zero-initialized. We will make a CL to Blink to explicitly set
wgpu::VertexStepMode::VertexBufferNotUsed for empty slots and change
the enum value to 2.

When abstract floats are supported, FloatLiteralExpression may hold values outside of the range of a f32. When we call FloatToString(), we may emit an 'inf', which is not a token for any backend.
Cast to f32 first, to ensure behavior remains consistent.
Note: Once the resolver materializes, and we constant fold, the backends shouldn't see any values outside of a f32.

Instead of vector-of-variant.
This:
• Makes it impossible to produce a mix of scalar variant types, which
would make no sense.
• Reduces the size of a Constant, by removing the union-tag from each
element.
Also clean up terminology. Rename 'Constant::Scalar' to
'Constant::Element'. Scalars are well-defined in WGSL, and with the
introduction of abstract-numerics, this no longer makes sense.

When enabled, unsuffixed literals will be treated as abstract numerics.
By having this disabled by default, we can build up the tests without
the risk of breaking production code.
This flag is enabled for resolver unit tests. This can safely be done
with no change in tested behavior, as all tests use the '_i' or '_u'
literal suffixes, so currently there are no tests that exercise abstract
numerics.
