Save isCanceled state and restore when rotation

- Create mIsCanceled field in FingerprintEnrollEnrolling
- Override onSaveInstanceState and save mIsCanceled state
- onCreate restore mIsCanceled
- shouldStartAutomatically() return mRestoring && !mIsCanceled
- Integrate FingerprintErrorDialog with "try again"-> Clear mIsCanceled

Bug: 237103873

dialog showing above fingerprint enrollment pad.
