core: Implement socket activation listeners (#6573)

Browse source 
* caddy adapt for listen_protocols

* adapt listen_socket

* allow multiple listen sockets for port ranges and readd socket fd listen logic

* readd logic to start servers according to listener protocols

* gofmt

* adapt caddytest

* gosec

* fmt and rename listen to listenWithSocket

* fmt and rename listen to listenWithSocket

* more consistent error msg

* non unix listenReusableWithSocketFile

* remove unused func

* doc comment typo

* nonosec

* commit

* doc comments

* more doc comments

* comment was misleading, cardinality did not change

* addressesWithProtocols

* update test

* fd/ and fdgram/

* rm addr

* actually write...

* i guess we doin' "skip": now

* wrong var in placeholder

* wrong var in placeholder II

* update param name in comment

* dont save nil file pointers

* windows

* key -> parsedKey

* osx

* multiple default_bind with protocols

* check for h1 and h2 listener netw
