Collections: Operator to duplicate a collection

When duplicating a layer collection directly linked to the view layer we copy
the collection and link it.

For all the not directly linked layer collectionns, we try to sync the layer
collection flags, overrides, ...

Also we make sure the new collection is right after the original collection.

We also expose this in RNA, via collection.duplicate().
