This enables indexing in `!foreach` and permutation with `list[permlist]`.

Enhancements in syntax:

- `list<int>` is applicable as a slice element.
- `list[int,]` is evaluated as not `ElemType` but `list<ElemType>` with a single element.

FIXME: I didn't apply new semantics to BitSlice.

TableGen: Prune convertInitListSlice and VarListElementInit

They were dedicated to constant version of list slice.
