Fix validation rules on inter-stage shader variables

This patch fixes the validation rules on inter-stage shader
variables when creating a render pipeline. In latest WebGPU
SPEC, each user-defined inter-stage shader variable should
always consume 4 inter-stage shader components no matter what
the component count is.

This patch also updates the minimum value of maximum inter-stage
shader components (from 60 to 64) and maximum inter-stage shader
variables (form 15 to 16) for WebGPU V1, and the minimum value of
`maxVertexOutputComponents` and `maxFragmentInputComponents` to
support WebGPU on Vulkan (from 64 to 68).
