Seth HillbrandandRoberto Fernandez Bautista 45da795668 Units are stored in the instance data 
At the moment, units are stored in the instance data, so when loading
the file, all symbols will have bbox for the first unit.  After calling
`UpdateUnit()`, we need to recache the rtree bounding boxes to get
correct hit tests

Fixes https://gitlab.com/kicad/code/kicad/issues/11681
