contrib/vcpkg-ports: remove openssl port

MSFT has merged PR to vcpkg which
added OPENSSL_NO_AUTOLOAD_CONFIG option

  https://github.com/microsoft/vcpkg/pull/18389

This means that we don't need to have our own openssl port
and instead we just add

  set(OPENSSL_NO_AUTOLOAD_CONFIG ON)

to our custom triplets.
