4/n: Remove challenge from choose/confirm, use new path
Biometric enrollment will not request a Gatekeeper HAT during
initial credential setup or credential confirmation anymore.
Instead, it is broken down into the following steps now.
Bug: 161765592
1) Request credential setup / confirmation to return a
Gatekeeper Password
2) Biometric enrollment will generate a challenge
3) Biometric enrollment will request LockSettingsService to
verify(GatekeeperPassword, challenge), and upon verification,
the Gatekeeper HAT will be returned.
Since both LockSettingsService and Biometric enroll/settings
make use of biometric challenges, this allows us to make the
challenge ownership/lifecycle clear (vs. previously, where
LockSettingsService has no idea who the challenge belongs to).

Test: RunSettingsRoboTests
Run the following on face/fingerprint devices
Test: Remove credential
adb shell am start -a android.app.action.SET_NEW_PASSWORD
Set up credential + fingerprint
Test: Remove credential,
adb shell am start -a android.settings.FINGERPRINT_SETTINGS
This tests the ChooseLock* logic in FingerprintSettings
Test: Set up credential,
adb shell am start -a android.settings.FINGERPRINT_SETTINGS
This tests the ConfirmLock* logic in FingerprintSettings
Test: Remove device credential, enroll fingerprint/face. Succeeds.
This tests the ChooseLock* returning SP path from
BiometricEnrollIntro
Test: With credential and fingerprint/face enrolled, go to
fingerprint/face settings and enroll. This tests the
ConfirmLock* path in Fingerprint/FaceSettings
Test: Remove device credential, enroll credential-only, enroll
fingerprint/face separately. Succeeds. This tests the
ConfirmLock* returning SP path in BiometricEnrollIntro
Test: In SUW, set up credential, then biometric. This tests
the ChooseLock* path in SUW
Test: In SUW, set up credential, go back, then set up biometric.
This tests the ConfirmLock* path in SUW
