Writable storage buffer in vertex shader is an optional feature.
It is not supported in many devices/OSes. WebGPU doesn't support
writable storage buffer in vertex shader. This change generates an
error for storage buffer binding for vertex shader stage, in order
to disallow writable storage buffer in vertex shader.
This change also adds a validation test and revises existing
end2end tests and validation tests accordingly.

Note that storage buffer and readonly storage buffer may not be
supported in vertex shader on OpenGL backend. In OpenGL Spec 4.6,
the minimum value of MAX_VERTEX_SHADER_STORAGE_BLOCKS is 0.

This change implements D3D12 backend for readonly storage buffer.
It uses SRV in root signature at API side and ByteAddressBuffer at
shader side (has already been done in spirv-cross) for readonly
storage buffer.

This change implements Vulkan backend for readonly storage buffer. It
also adds a few end2end tests to verify the implementation.

The change adds multiple write then multiple read tests for gpu memory
synchronization test. It covers all common usages: write into storage
buffers, then read the data as vertices, indices, and uniforms.
The different usages are done via separate buffers, and one mixed buffer
via two tests.
I added two uniform buffers/usages in these two tests. I will replace one
uniform buffer by readonly storage buffer later. Then all readonly usages
will be covered. So it is also useful to verify the upcoming implementation
on backend for readonly storage buffer.

This change adds GPU memory synchronization tests for buffer. The tests cover
data flow from render pass to compute pass via storage buffer, and vice versa.
It is the last one for the series of memory sync tests for buffer.

This CL adds end2end tests for memory synchronization tests for buffer.
It adds a few tests that iterate data read-add-write operations a few
times in buffer for compute and render respectively, and verifies
that data dependency among interations is well synchronized.
