http: added options for allowing HTTP/0.9 responses

Added CURLOPT_HTTP09_ALLOWED and --http0.9 for this purpose.

For now, both the tool and library allow HTTP/0.9 by default.
docs/DEPRECATE.md lays out the plan for when to reverse that default: 6
months after the 7.64.0 release. The options are added already now so
that applications/scripts can start using them already now.

Fixes #2873
Closes #3383
