Make ShadowPendingIntent implement is___ methods of PendingIntent

The methods isActivity, isBroadcast, isForegroundService, isService
and isImmutable were added in API level 31. They currently throw
NullPointerException when called in the simulated Robolectric
environment.

This change implements these methods using the pre-existing
is___Intent methods of ShadowPendingIntent.
