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

Tells curl to use the specified public key file (or hashes) to verify the
peer. This can be a path to a file which contains a single public key in PEM
or DER format, or any number of base64 encoded sha256 hashes preceded by
'sha256//' and separated by ';'.
When negotiating a TLS or SSL connection, the server sends a certificate
indicating its identity. A public key is extracted from this certificate and
if it does not exactly match the public key provided to this option, curl will
abort the connection before sending or receiving any data.
PEM/DER support:
7.39.0: OpenSSL, GnuTLS and GSKit
7.43.0: NSS and wolfSSL
7.47.0: mbedtls
sha256 support:
7.44.0: OpenSSL, GnuTLS, NSS and wolfSSL
7.47.0: mbedtls
Other SSL backends not supported.
