[3.7] gh-96848: Fix -X int_max_str_digits option parsing (#96988) (#97576)
Fix command line parsing: reject "-X int_max_str_digits" option with
no value (invalid) when the PYTHONINTMAXSTRDIGITS environment
variable is set to a valid limit.
(cherry picked from commit 41351662bcd21672d8ccfa62fe44d72027e6bcf8)
