Prevent frequent process killing when multiple permissions are revoked at the same time.

When we test CTS case
HealthConnectDeviceTest#testToVerifyNoPermissionChangeLog, a large
number of health-related permissions will be cyclically revoked in the
case, which will cause the handler to accumulate a large number of
killUid runnables. If the App process is started immediately, the newly
started App will be killed immediately.
