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.
