df12508b - use `experimentalHttpsServer` flag when determining image optimizer protocol (#55988)

use `experimentalHttpsServer` flag when determining image optimizer protocol (#55988) Inferring the protocol from the request meta is not reliable when the next server is running over `http` but sitting behind an https proxy. This instead plumbs the experimental https flag through to the optimizer so we can more reliably determine the protocol Fixes #55971
