uucore: format: num_parser: Add value to Overflow error

Browse source 
When parsing integers, we should still return the min/max value
of the type (depending on the type), and wrap that in the error.

We need to refactor the map function to handle this case better,
and add an extract function to get the value out of an error
(if any).

This fixes the integer part of #7508.
