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.

Update child objects to ref the device. This allows them to outlive
the device, making the implementation more robust such that it is OK
to drop the device before other objects.
Dropping the last external reference to the device is currently an
implicit device.destroy(). This destruction breaks possible ref cycles
where the device refs internal objects which have a back ref to the
device.

When we initialize the dst texture before T2T copy, we clear a
buffer with zeros and do a B2T copy in order to initialize the
texture. The T2T copy may only copy a subrect of the texture's
subresource, so does the initialization via B2T copy. As a result,
the buffer can store compact zeros for that exact subrect and then
do an exact B2T copy to initialize that area.
However, the current B2T copy uses incorrect data layout for the
buffer, making some part of the dst texture uninitialized, and
even leading to D3D12 runtime validation errors sometimes if it
goes beyond the boundary of staging buffer pool (4MB).
This change fixes this bug via using the exact height of copy area
to replace dataLayout.rowsPerImage (unnecessary padding rows included)
for the height of each depth image for 3D textures.

In this patch a WGSL extension allow list is added in DeviceBase, and
a validation is added in shader module base initialization to make sure
all extensions used in the WGSL program are in the allow list. This
patch also rename the `ValidateShaderModuleDescriptor` to
`ValidateAndParseShaderModule`, which is more descriptive for what it

On D3D12 backend, external texture holds mD3D11on12Resource which caches
D3D11on12Resources and guarding by refptr. The texture will released this ref
until destructor works.
This model leaks the gpu memory if client fails to release all the ref to
the texture.
Instead, external texture also provides a method called "Destroy". It is
called more eagerly and means the external texture is in the end of lifecycle.
So thid CL moves the ref reset of D3D11on12Resource into Destroy(). This prevents
unexpected gpu memory leak caused by client missing ref release call.
