Keep the notification shade open for smart replies

Currently when the user taps on a smart reply button from a locked
screen, we ask for a pattern/password and then close the notification
shade. This is inconsistent with the unlocked case and with how inline
replies are handled.

Set mLeaveOpenOnKeyguardHide to true when handling smart reply clicks.
Also simplify and rename the method in KeyguardDismissHandler to make
this new behaviour clearer.

Bug: 77841506
Test: Tap on a smart reply from the lockscreen, then unlock.
