lib: connect/h2/h3 refactor
Refactoring of connection setup and happy eyeballing. Move
nghttp2. ngtcp2, quiche and msh3 into connection filters.

 - eyeballing cfilter that uses sub-filters for performing parallel connects
 - socket cfilter for all transport types, including QUIC
 - QUIC implementations in cfilter, can now participate in eyeballing
 - connection setup is more dynamic in order to adapt to what filter did
   really connect.  Relevant to see if a SSL filter needs to be added or
   if SSL has already been provided
 - HTTP/3 test cases similar to HTTP/2
 - multiuse of parallel transfers for HTTP/3, tested for ngtcp2 and quiche

 - Fix for data attach/detach in VTLS filters that could lead to crashes
   during parallel transfers.
 - Eliminating setup() methods in cfilters, no longer needed.
 - Improving Curl_conn_is_alive() to replace Curl_connalive() and
   integrated ssl alive checks into cfilter.
 - Adding CF_CNTRL_CONN_INFO_UPDATE to tell filters to update
   connection into and persist it at the easy handle.

 - Several more cfilter related cleanups and moves:
   - stream_weigth and dependency info is now wrapped in struct
     Curl_data_priority
   - Curl_data_priority members depend is available in HTTP2|HTTP3
   - Curl_data_priority members depend on NGHTTP2 support
   - handling init/reset/cleanup of priority part of url.c
   - data->state.priority same struct, but shallow copy for compares only

 - PROTOPT_STREAM has been removed
   - Curl_conn_is_mulitplex() now available to check on capability

 - Adding query method to connection filters.
   - ngtcp2+quiche: implementing query for max concurrent transfers.

 - Adding is_alive and keep_alive cfilter methods. Adding DATA_SETUP event.
   - setting keepalive timestamp on connect
   - DATA_SETUP is called after the connection has been completely
     setup (but may not connected yet) to allow filters to initialize
     data members they use.

 - there is no socket to be had with msh3, it is unclear how select
   shall work

 - manual test via "curl --http3 https://curl.se" fail with "empty
   reply from server".

 - Various socket/conn related cleanups:
   - Curl_socket is now Curl_socket_open and in cf-socket.c
   - Curl_closesocket is now Curl_socket_close and in cf-socket.c
   - Curl_ssl_use has been replaced with Cur_conn_is_ssl
   - Curl_conn_tcp_accepted_set has been split into
     Curl_conn_tcp_listen_set and Curl_conn_tcp_accepted_set
     with a clearer purpose
