fix Image when used with `--experimental-https` (#55775)
The IPC request to `imageOptimizer` assumed the server was listening on http, so this updates it to pull the protocol from `getRequestMeta` instead. This also adds the option to pass in a path to the CA Root so that the dev server can add it to `NODE_EXTRA_CA_CERTS`
Closes NEXT-1646
Fixes #55706
