Rollup merge of #107662 - cjgillot:copy-projection, r=oli-obk 
Turn projections into copies in CopyProp.

The current implementation can leave behind projections that are moved out several times.

This PR widens the check to turn such moves into copies: a move out of a projection of a copy is equivalent to a copy of the original projection.
