services: tor: Add support for pluggable transports.

Pluggable transports are programs that disguise Tor traffic, which
can be useful in case Tor is censored.  Pluggable transports
cannot be configured by #:config-file file exclusively because Tor
process is run via 'least-authority-wrapper' and cannot have access
to transport plugin, which is a separate executable (Bug#70302,
Bug#70332).

* doc/guix.texi (Networking Services): Document 'tor-transport-plugin'
data type and 'transport-plugins' option for 'tor-configuration.
* gnu/services/networking.scm: Export
'tor-configuration-transport-plugins', 'tor-transport-plugin',
'tor-transport-plugin?', 'tor-plugin-role',
'tor-plugin-protocol', and 'tor-plugin-program'.
(<tor-configuration>): Add 'transport-plugins' field.
(<tor-transport-plugin>): New variable.
(tor-configuration->torrc): Add content to 'torrc' computed-file.

doc: Refer to ‘iso-codes’, not ‘iso-codes/pinned’.

This effectively reverts 8e5c8303a414719c19a597247674be87fd500d45, which
was unnecessary in this case and would break when evaluating
‘doc/build.scm’ against a previous Guix revision where
‘iso-codes/pinned’ is unbound.

* doc/build.scm (localization-helper-module): Use ‘iso-codes’ rather
than ‘iso-codes/pinned’.
