Allow for activities to resumed if keyguard is occluded.

A previous changelist enforced that activities would not be resumed
if the keyguard is locked. However, this prevents activities that
show above the keyguard from resuming.

This changelist adjusts this check to account for occlusion.

Fixes: 74585178
Test: Lock screen, fingerprint unlock, verify activity is resumed.
Test: Set alarm, lock screen, verify alarm shows above lock screen
      resumed.
