Disallow storage buffer binding in vertex shader

Browse Source 
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.
