Lib reload/relocate: Improve performances.

Reduce amounts of viewlayer updates during remapping while relocating
libraries. Gives some improvements on relocating process, depending on
complexity of existing scene and reloaded libraries, whether there is
liboverrides to resync, etc., can give up to 10% speedup.
