Use macro not swash for utf8 quotemeta

The rules for matching whether an above-Latin1 code point are now saved
in a macro generated from a trie by regen/regcharclass.pl, and these are
now used by pp.c to test these cases.  This allows removal of a wrapper
subroutine, and also there is no need for dynamic loading at run-time
into a swash.

This macro is about as big as I'm comfortable compiling in, but it
saves the building of a hash that can grow over time, and removes a
subroutine and interpreter variables.  Indeed, performance benchmarks
show that it is about the same speed as a hash, but it does not require
having to load the rules in from disk the first time it is used.
