Add a validation to ensure zero-attribute for unused vertex
buffer slots (stepMode = VertexBufferNotUsed).
Fuzz tests found that non-zero-attribute with unused vertex
buffer can cause an error in swiftshader.
We may be able to think input data having non-zero-attribute
with unused vertex buffe is malformed. Refusing such input
data can avoid the error.

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.

The WebGPU spec says that a validation error is produced if there is a
color target in the pipeline descriptor that has writeMask!=0 while
there are no shader outputs for this target. In Dawn format==undefined
is used as a tag that the color target is not present, so writeMask is
allowed to be 0 if format==undefined. (the validation in the case where
format!=undefined was already present).

- Adds testing for Vulkan pipeline caching.
- Removed redundant VK_NULL_HANDLE and use explicit {} initialization for 0 handles when necessary.
- Adds some const qualifiers where applicable and useful.
- Removes overloaded GetCacheKey (const/non-const) versions and exposed the cache key member directly for modifiers in derived classes.

This CL updates the clang format files to have a single shared format
between Dawn and Tint. The major changes are tabs are 4 spaces, lines
are 100 columns and namespaces are not indented.

The current presubmit has the filter inverted so it would only attempt
to match the filtered files. The file name also has to be converted to
`LocalPath` otherwise it's attempting to compare a python object to a

This Cl moves the cpp includes to above the project includes fixing up
the build/include_order issues and enabling the lint check.
A couple includes are marked as NOLINT as the c header has to come after
the project header due to setting defines.
