Subject: [PATCH] BUILD(crypto): Migrate to OpenSSL 3.0-compatible API

OpenSSL 3.0 deprecated several low-level APIs and the usage of them
caused errors/warnings that prevent the binary from being built against
OpenSSL 3.0.
Some primitive efforts have been made in #5317 but were incomplete.
This commit follows https://www.openssl.org/docs/man3.0/man7/migration_guide.html,
https://code.woboq.org/qt6/qtopcua/src/opcua/x509/qopcuakeypair_openssl.cpp.html,
and clears all errors/warnings related to the usage of deprecated APIs.
