utf8.c: Add function to create inversion of swash
This adds _swash_inversion_hash() which takes a mapping swash and returns
a hash that is the inverse relation. That is, given a code point, it
allows quick lookup of all code points that map to it.
The function is not for public use, as it will likely be revised, so is
not in the public API, and it's name begins with underscore.
It does not deal with multi-char mappings at this time, nor other swash
complications.
