Bump macOS build recommendations to OpenSSL v3.0 (#1112)

* Simplify recipes by:
1. removing references to 3.7 which will be end-of-life shortly
   and otherwise would require including OpenSSL 1.1.1 libs.
2. removing MacPorts recipe for 3.10 and earlier because there
   are conflicts with the use of --with-openssl and the use of
   CPPFLAGS/LDFLAGS.
