Only consider notification launches from keyguard in KeyguardSurfaceBehindInteractor

To avoid showing the keyguard unnecessarily when launching a
notification intent from the keyguard GONE state.

Test: with keyguard_wm_state_refactor flag enabled, tap a notification
with an intent when the keyguard isn't showing (ie: shade over the
launcher). Observe that StatusBarKeyguardViewManager#show never gets
called (requires manually logging since something else, when flexiglass
isn't enabled, gates the keyguard from actually showing).
Test: atest KeyguardSurfaceBehindInteractorTest
