RESTRICT AUTOMERGE Show primary bouncer on TOUCH_OUTSIDE

The notification shade isn't showing over occluding apps, so it
doesn't intercept touches for the alternate bouncer. Therefore,
the AlternateBouncer needs to rely on TOUCH_OUTSIDE.

This was fixed in udc-dev but also needs to be fixed in tm-qpr.

Test: atest StatusBarKeyguardViewManagerTest
Test: manually bring up altBouncer with UDFPS
over an occluding app and tap outside UDFPS area,
the primary bouncer will show
