Provide fingerprint options for SET_NEW_PASSWORD intent

1) Added a trampoline activity to display SET_NEW_PASSWORD intent.
2) On devices that have fingerprint sensor and have no enrolled fingerprint,
   ChooseLockGeneric handles the SET_NEW_PASSWORD intent by providing
   fingerprint + {PIN/PATTERN/PASSWORD} and skip fingerprint options.

Test: See below
1) Auto
   make RunSettingsRoboTests
2) Manual
   a) Fingerprint + pattern
      i) $ adb shell am start -a android.app.action.SET_NEW_PASSWORD
      ii) Click Pixel Imprint + Pattern.
      iii) Set a pattern lock.
      iv) Can enroll a fingerprint.
   b) Pattern
      i) $ adb shell am start -a android.app.action.SET_NEW_PASSWORD
      ii) Click Continue without Pixel Imprint
      iii) A list of unlock options, without fingerprint option, is shown.
      vi) Select and enroll a pattern lock
   c) Has an existing password
      i) $ adb shell am start -a android.app.action.SET_NEW_PASSWORD
      ii) Setting app asks for password input.
      iii) Enter password and click "Continue without Pixel imprint".
      vi) No password is asked. A list of unlock options, without fingerprint option, is shown.
      v) Select and enroll a pattern lock
   d) Work profile
      i) Create a work profile
      ii) adb shell am start --user x -a android.app.action.SET_NEW_PASSWORD. X is the work profile user id.
      iii) Click Pixel Imprint + Pattern.
      iv) Set a pattern lock.
      v) Can enroll a fingerprint.
