curl: add long option '--out-null' 
Add a new commandline option --out-null that discards all
response bytes into the void. Replaces non-portable use of
'-o /dev/null' with more efficiency.

Feature added in 8.16.0

Closes #17800

--out-null

Discard all response output of a transfer silently. This is the more efficient and portable version of

curl https://host.example -o /dev/null

The transfer is done in full, all data is received and checked, but the bytes are not written anywhere.
