Rewrite ASN1_STRING_print_ex escaping.

The original implementation uses a table generated by a Perl script,
and then relies on some subset of ASN1_STRFLGS_* constants overlapping
with CHARTYPE_* constants, while masking off the ones that don't align.

Allocating ASN1_STRFLGS_* constants is already complex with the
XN_FLAG_* interaction. Avoid the additional CHARTYPE_* interaction by
just writing out what it's recognizing in code. If you ignore
CHARTYPE_PRINTABLESTRING (which is unused), that table is just
recognizing 9 characters anyway.

Also this gets charmap.h out of the way so I can clang-format every file
in here without having to constantly exclude it.
