[0.4.9][NTUSER][USER32] Tracking menu CORE-17338 (#4048), [EXPLORER] Send WM_POPUPSYSTEMMENU asynchronously (#4047) CORE-16353

Browse source 
This prevents the tracking menu from erroneously closing itself right after it was opened in some cases.
Fixes CORE-17338 which got unhidden by 0.4.15-dev-1126-g 58b0558f94
And fixes CORE-15760 which got unhidden by SVN r74972 == git 19dd22d422

Since both symptoms look very similar but the unhiding revisions did differ,
that could mean we do have some kind of race condition here.
I guess this fix is more like a workaround.
