Tidy up integer parsing (#17339)

The parse_integer function was previously made to reject negative values by
default in https://github.com/element-hq/synapse/pull/16920, but the
documentation stated otherwise. This fixes the documentation and also:

- Removes explicit negative=False parameters from call sites.
- Brings the negative default of parse_integer_from_args in alignment with
  parse_integer.
