New description:

 As documented in #17548, #17956, #17920, there are several bugs in
 !IntegerListsLex which also have implications for !Partitions and
 !Compositions. This branch reimplements !IntegerListsLex.

 See also #18055 and #18056 for followups.

 Remaining design points:

 - Do we want to keep the feature that after `min_length`, lists are
 "considered up to trailing zeroes".
 - Renaming all the attributes (`.floor`, ...) to private attributes
 - Double check to logic for improper lexicographic iterability detection
