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

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 58b0558f94abee52ce1c261063d4f4b884e96310
And fixes CORE-15760 which got unhidden by SVN r74972 == git 19dd22d42218da03ab748879aa3c3e288f41697e

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.
