ngtcp2: share common functionality

Share common functions/structs between ngtcp2 HTTP/3 and the proxy
version.

Fix bugs in proxy implementation when it comes to stream and pollset
handling and transfer lifetimes.

Curl_multi_xfer_sockbuf_borrow: work without multi

When a connection gets shutdown by a share, the easy handle used is
share->admin and it does not have a multi handle. In that case let
Curl_multi_xfer_sockbuf_borrow() allocate a buffer to be freed on
release.

This happens when a TLS filter sends its last notify through a HTTP/3
proxy tunnel.

Closes #21871
