nir: add shader_info::tess::tcs_same_invocation_inputs_read(_indirect)
We need both the same-invocation usage mask and cross-invocation usage mask. The AMD reason is below.
Cross-invocation TCS input access doesn't prevent the same-invocation fast path in AMD hw because it's just a different way to load the same data, and we want to use both paths for the same TCS input based on the load instruction. The fast path can't be used for indirect access, which is gathered separately for same-invocation access.
