Removing some workarounds that are no longer needed in BCB11

- Not sure if the "push -vi" workaround was obsoleted by BCB11, but it does not seem to be needed anymore
- TCustomPathLabel.CMStyleChanged workaround was obsoleted by change in TCustomLabel.CMStyleChanged
- status bar scaling is not implemented in TCustomStatusBar.ChangeScale
