beam_validator: Tighten and simplify map validation code
The assert_strict_literal_termorder/1 function is used to validate the get_map_elements and has_map_fields instructions. In neither case is it useful to allow an empty lists of fields, so we should no longer allow an empty list. The mmap/2 function is cute, but it is used in only one place, so it is much simpler to write a special-purpose function to extract the keys from the list of map pairs.
