Fix PrimitiveId builtin check for Vulkan

According to Vulkan spec 1.1.72:

> The PrimitiveId decoration must be used only within fragment,
> tessellation control, tessellation evaluation, and geometry shaders.

> In a tessellation control or tessellation evaluation shader, any
> variable decorated with PrimitiveId must be declared using the Input
> storage class.

We were enforcing that PrimitiveId can only be used with Output
storage class for TCS and TES before.
