The new --disable-liboverride-auto-resync commandline option will prevent
running liboverride auto-resync immediately after loading a blendfile.
This is an alternative way to setting the User Preferences Debug option
`No Override Auto Resync`.
-------
Some quick performances tests:
Loading a Gold production file goes from 26.5s to 25.9s.
Combined with the recent `--disable-depsgraph-on-file-load` option, it
goes from 3.5s to 2.9s, so another nice extra 15% speedup when only
bare-metal blendfile loading is needed.
