gibaseinfo: Remove need for casting for gi_base_info_ref() and unref()

Browse Source 
Just like is done with `g_object_{ref,unref}()`, make these functions
take a `void*` rather than a `GIBaseInfo*`, since they’ll most likely be
called with a type which is derived from `GIBaseInfo*` rather than a
`GIBaseInfo*` itself.

Add some runtime type checks to make up for lowering the compile time
type safety.
