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.

Previously, the device/adapter were all created on the service-side
of a test, and then injected into the client side. Injected devices
and adapters do not support querying limits and features.
This CL changes setup so that adapter and device creation is always
initiated by the client - and the implementation on the service side
may be overridden for test fixture-specific behavior.
It also adds more fuzzing coverage since the fuzzers can now also
create adapters and devices.

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.

A list of errors, `infringingLimits`, is added to EntryPointMetadata.
During shader reflection, instead of directly bubbling limit errors up,
they are stored in this list and check only later during pipeline
creation.
Several ShaderModule tests are reworked to create a pipeline to check
for the validation of these limits. For the IO variable limits the tests
needed to be reworked to check for strings in the error messages because
since IO structs have to match between VS and FS, if one failed the
other failed too. (so it's no possible to target the validation of one
of these in particular)

imcompatible with MTLTextureType2DMultisample, even if the layer
count is 1.
MTLTextureType2DMultisampleArray is not supported until macOS 10.14
and iOS 14.0.
Further, the view type must match between the API and the shader.
a 2D view array requires texture2d_array in MSL.
It would be inconsistent to allow 1-layer 2D arrays which internally
get translated as (non-array) MTLTextureType2DMultisample. You would
expect to need to use texture2d_ms_array in the shader.
