comctl32: LVN_ITEMCHANGED notification should be sent for each item when group selected for ~LVS_OWNERDATA

[Nikolay Sivov]

A 7-zip file manager is obviously affected by missed notification when group
selected (with Shift pressed). Selection count and file sizes aren't updated.
Count update's based on per item notification: I'm saying that after looking
sources and some message spying on WinXP.

Changelog:
    - (try2) added a fixme comment for unimplemented LVN_ODSTATECHANGED
    - LVN_ITEMCHANGED notification should be sent for each item when group selected for ~LVS_OWNERDATA
