Curl_http(), decomplexify

Split out adding of individual request headers into a switch. Check
the connection http version only on fresh connections, use separate
methods.

Add TE: header directly without allocation. Add bit for indicating
Connection: header has been added and custom headers should not do
that again.

Closes #18444
