tests/extmod/json_loads_int_64.py: Add test cases for LONGINT parse.

These tests cover the use of mp_obj_new_int_from_str_len when
mp_parse_num_integer overflows the SMALLINT limit, and also the case where
the value may not be null terminated.

Placed in a separate test file so that extmod/json test doesn't rely on
bigint support.
