ISLE: Re-implement ValueSlice (#3784)

Browse Source 
The current definition of `ValueSlice` is not usable, since any call to
a constructor returning a `ValueSlice` will extend the mutable borrow
on the context taken by the constructor call, with the result that it
cannot be passed to any other constructor ever.

Re-implement `ValueSlice` as a pair of a `ValueList` identifer plus an
offset into the list.  This type can simply be copied without requiring
a borrow on the context.
