[ASTERIXDB-2417][COMP] Fix issues with LIMIT clause

- user model changes: yes
- storage format changes: no
- interface changes: no

Details:
- Fixed NPE in optimizer when limit/offset is non-integer
- Allow float/double values that are integers in limit/offset
- Make consistent limit/offset value types (integer) between
  runtime and optimizer rules
- Add internal function treat-as-integer() that returns integer
  if input number conforms to the integer type or fails otherwise
