Don't reinstall { darwin any } ports after OS major version upgrade

[breun (Nils Breunese)]

After a macOS major version upgrade, when I upgrade my ports, I notice that port outdated shows (platform darwin 22 ≠ 23) for ports that use platforms { darwin any }, and they get reinstalled when I run sudo port upgrade outdated, which I think is unnecessary. It would be nice if these ports could be considered not outdated, so they also won't get reinstalled.

In 1b4db00efac269d81cc4e461ac5f6e2aa4a60969/macports-base (master):

Allow "any" in registry os_{platform,major}

Now setting these values on installation the same way as the platform
string in the archive filename. Also don't consider a port outdated due
to platform mismatch if it has an "any" value for these.
