Fix the Fingerprint enrollment page's title text creates a truncate

problem when it needs three lines on the R4 device

Add padding between title and lottie animation, and adjust UDFPS
enroll view top margin.

Bug: 269437675

Test: manually test,
1.Go to Go to Settings > Security > Fingerprint Unlock >
Set up Fingerprint Unlock > How to set up your fingerprint >
Touch & hold the fingerprint sensor ,
then to start enroll fingerprint.

2. Always keep the finger in the same position,
then let the title become a three line description
“Change the position of your fingerprint slightly each time”.

3. Check the UI if it has been fixed.

Test: make RunSettingsRoboTests ROBOTEST_FILTER="com.android.settings
.biometrics.fingerprint.FingerprintEnrollEnrollingTest"
