[simlauncher] Add missing weak frameworks to simlauncher (#6955)

Things often work fine without them but, in a few cases, you can run into
some weird problems.

Add better comments for synchronization... until we add some tests [1]

Replace the following, cancelled PR
* BackgroundTask #6949
* INcomingCallNotifications #6954
* LinkPresentation #6953
* PencilKit #6950
* SoundAnalysis #6952

[1] #6951
