openssl: import 3.5.5

This change adds OpenSSL 3.5.5 from upstream [1].

The 3.5.5 artifact was been verified via PGP key [2] and by SHA256 checksum [3].

This is a security release, but also contains several bugfixes. All of
the CVE-worthy issues have already been addressed on the target
branch(es), so the net-result is that this is a bugfix release.

More information about the release (from a high level) can be found in
the release notes [4].
