cmdline/docs: add a required 'multi' keyword for each option
The keyword specifies how option works when specified multiple times:

 - single: the last provided value replaces the earlier ones
 - append: it supports being provided multiple times
 - boolean: on/off values
 - mutex: flag-like option that disable anoter flag

The 'gen.pl' script then outputs the proper and unified language for
each option's multi-use behavior in the generated man page.

The multi: header is requires in each .d file and will cause build error
if missing or set to an unknown value.

Closes #9759

Specifies which cipher suites to use in the connection if it negotiates TLS
1.3. The list of ciphers suites must specify valid ciphers. Read up on TLS 1.3
cipher suite details on this URL:
https://curl.se/docs/ssl-ciphers.html
This option is currently used only when curl is built to use OpenSSL 1.1.1 or
later. If you are using a different SSL backend you can try setting TLS 1.3
cipher suites by using the --ciphers option.
