[AF_RXRPC]: Key facility changes for AF_RXRPC
Export the keyring key type definition and document its availability.
Add alternative types into the key's type_data union to make it more useful.
Not all users necessarily want to use it as a list_head (AF_RXRPC doesn't, for
example), so make it clear that it can be used in other ways.
