Bob Nystrom 08618abc5d fix: allow empty range subscripts [0..-1] and [0...0] on empty lists ...

Add special case in list_subscript native to return a new empty list when
the source list is empty and the requested range is [0..-1] (inclusive) or
[0...0] (exclusive). This enables using list[0..-1] as a universal copy
idiom that works even for empty lists. Update the List.+ operator to use
this idiom instead of manual iteration. Add test cases for both range
forms on empty lists.
