girepository: Add length ‘out’ arguments to several getter methods

Browse Source 
This makes them consistent with the other getter methods in
`GIRepository` which return lists/arrays. It’s useful to return the
length, as that means the caller doesn’t have to work it out by
iterating over the entire array.
