Implement SFPS “require screen on to auth”
Creates new setting on SFPS to require screen on before unlocking a device. Also sets up toggles for this setting at the end of fingerprint enrollment and on the fingerprint settings page, and adds tests to verify expected behavior. Test: make RunSettingsRoboTests ROBOTEST_FILTER=FingerprintSettingsRequireScreenOnToAuthPreferenceControllerTest Fixes: 249169615 Fixes: 245343077 Fixes: 248530806 Change-Id: Id588796426d071860b3cc2af9ec5798c0027c202
