t/charset_tools.pl: Improve function names

'latin1_to_native' and 'native_to_latin1' actually operate on all code
points, not just the ranges implied by their names.  This commit changes
the names to reflect that, to 'uni_to_native' and 'native_to_uni'.
The old names have only been available since 5.21, so there is no
backcompat issue.
