Adding MSDL haptics to interactions with lockscreen shortcuts.

The KeyguardQuickAffordanceHapticViewModel is introduced to make use of
data flows about interactions with quick affordances. With these, the
view-model produces a Flow of haptic states, which can then be collected
to play the corresponding haptics using the MSDL player in SysUI.
