[SSDP] add schema(Print &) const (#6798)

Browse Source 
* [SSDP] add `schema(Print &) const`

Supercedes #2806

Make SSDP::schema(WiFiClient&) use a by-ref (reduce stack use)

Add a SSDP::schema(Print&)

From @Palatis' original PR:
useful when using AsyncWebServer.

* Use ip.toString, only export Print& schema interface

Because WiFiClient inherits a Print interface, replace the
::schema(WiFiClient&) with ::schema(Print&) which is source compatible
with existing code and allows the functionality requested in the initial
PR.

Use ip.toString() in the templates instead of breaking up the octets of
the address.

* Fix compile errors and backwards compatibility
