Lua API: Add register_on_chatcommand to SSM and CSM (#7862)
Allows catching a chatcommand call just after the command and the
parameters are parsed but before its existence is checked and before the
corresponding function is run. Returning `true` from a callback function
will prevent default handling of the command leaving mods to handle the
command manually.
