sout: add ES string ID to the `Add` wrapper

The new ES string ID was added initially in the core for playback
scenario allowing the user to have a readable and guaranteed unique
representation of each ES.

Introducing it in stream output will allow users to specify ESes to
stream out filters with more precision than with legacy ES ID.
ES ID has the disadvantage to only be unique per demux, hence, a
multiple demux scenario often provided multiple ES with the same ID.
Strings ID are guaranteed to be unique, regardless of the number of
demuxes the input manages.

This patch only prepare the `Add` wrapper to properly split the addition
of the unique and **non-null** string to the `pf_add` callback. This is
done in that order mainly not to break bisect in the next patches that
implement the ID forwarding logic for stream out filters.

input: create a specific CC string ID for sout

Since we send the whole side data, we need a string ID specific to
stream out Closed captions.

sout: bridge: suffix and forward ES string ID

The string ID needs to be stored and modified (for uniqueness at the
bridge output).

sout: gather: duplicate and forward ES string ID

The string ID of the first gathered ES is forwarded to the next stream.
As the validity of the string is only guaranteed for the lifetime of the
input, `--sout-keep` scenario force us to duplicate the fist string ID
here.
