hle: Tidy-up ServiceNotImplementedException (#2535)
* hle: Simplify ServiceNotImplementedException

This removes the need to pass in whether the command is a Tipc command or a Hipc command to the exception constructor.

* hle: Use the IPC Message type to determine command type

This allows differentiating between Tipc and Hipc commands when invoking a handler that supports handling both Tipc and Hipc commands.
