VST3: retain I/O from older versions (bump session format)

Browse Source 
A VST3 plugin can have additional busses which were not
available in older versions of Ardour. For compatibility
reasons those should remain unconnected. This is achieved
by using a custom I/O config  (same way a user would configure
this).
