Only show auth ripple on keyguard

- Don't show the ripple on the biometric prompt
- Don't show the ripple on face auth if bypass is disabled
- Don't show the ripple if we're not authenticating (ie: brought to
bouncer for strong auth requirement)

- Never show the udfps icon if strong auth is required
