encoding/asn1: allow '&' in PrintableString fields
There are, unfortunately, intermediate CA ceritificates in circulation
that contain the invalid character '&' in some PrintableString fields,
notably Organization Name. This patch allows for ampersand
to be parsed as though it is valid in an ASN.1 PrintableString.
Fixes #22970
