DepsGraph: Multi ViewLayer Selection

When using multiple viewlayers and switching between them the selection
gets buggy. The reason for this is that the select_id is updated based
on the index in the viewlayer. This makes the select_id not unique as
objects might be shared or not shared at all.

This fix will update the select_id on all objects in main. This will be triggered in all the selection operators.
