esp_http_server: fix default control port for HTTPS configuration

For simultaneous HTTP and HTTPS server use-case, default configurations
set same control socket port and hence one of the server initialization
fails with an error "error in creating control socket".

This commit modifies default initializers to use different control
socket port in HTTP vs HTTPS server case.

Closes IDFGH-8719
