[SHELL32][BROWSEUI] CopyMoveToMenu must initialize without a PIDL folder (#7047)
- IShellExtInit cannot rely on a folder PIDL being present
- Use common QueryContextMenu function for both menu items
- Allow copy to the same folder
- Disable toolbar buttons when the selection is not valid
- Minor DefView cache enhancement and bugfixes
