cmStringAlgorithms: Add cmStrToLong and cmStrToULong

This adds the following functions to cmStringAlgorithms:
- `cmStrToLong`: moved from `cmSystemTools::StringToLong`
- `cmStrToULong`: moved from `cmSystemTools::StringToULong`

Overloads of the given functions for `std::string` are added as well.
