Introduce openssl3 and pcre2 by default
Introduce openssl3 and pcre2 by default

The httpd-2.4.53 release introduced support of the current openssl-3.0
and pcre2-10.x releases. Make these the default, and leave the existing
logic so that one can tweak the Makefile.gather pointers to revert back
to the legacy openssl-1.1.1 or pcre-8.x releases.
