ASoC: SOF: sof-client: Add support IPC4 message sending

In order to be able to send an IPC4 message, the
sof_client_ipc_tx_message() needs to parse the tx message differently to
extract the size.

The IPC notification registration is done by providing the notification
type and the whole message is passed to the client when a match is found.
