[COMCTL32] Pass a couple of window messages to the active page of property sheets (#9239)

Browse Source 
CORE-20681

Send `WM_ACTIVATE` and `WM_ACTIVATEAPP` to the property sheet active page.
And do the same with `WM_ENABLE`, `WM_QUERYENDSESSION`, `WM_ENDSESSION`,
and `WM_DEVICECHANGE`, after sending them to the tab control first.

Similar in spirit to commit d09c3d0af8.
