[SHELL32][SDK] SHChangeNotify: Re-work Part 1 (#6898) 
Making shell change notification implementation better.
Now recycle bin icon change is working.
JIRA issue: CORE-13950
JIRA issue: CORE-19591
JIRA issue: CORE-11453
- Delete SHSimpleIDListFromPathA/W hacks.
- Translate simple PIDLs (coming from SHSimpleIDListFromPathA/W)
  in CDefView::OnChangeNotify method.
- Add CDefView::LV_RefreshIcons method for SHCNE_UPDATEIMAGE
  change event.
- Rename CDefView::LV_ProdItem method as CDefView::LV_UpdateItem.
- Call SHUpdateRecycleBinIcon in SHFileOperationW function.
- Half-implement SHUpdateRecycleBinIcon.
- Call SHChangeNotify in DeleteExt function.
