Happy Eyeballs: add resolution time delay
HEv3 describes conditions on when first connect attempts shall be
started.
https://www.ietf.org/archive/id/draft-ietf-happy-happyeyeballs-v3-01.html
Chapter 4.2

libcurl now waits 50ms for AAAA and HTTPS results (when requested) to
return before continuing with the connect.

Added HTTPS-RR to the "was resolved" information info message. Changed
logging of HTTPS-RR to a one-liner with RFC 9460 like formatting. This
way the user can see if/what was resolved and used in connecting.

Closes #21354
