Hide description text view if there is overlap.

1. Includes udfps enroll view in xml files and cleans up FingerprintEnrollEnrolling adding udfps enroll view code.
2. Clean up SETTINGS_SHOW_UDFPS_ENROLL_IN_SETTINGS flag.
3. If description text view has overlap with udfps progress view, hide the description text view.

Test: atest FingerprintEnrollEnrollingTest
Test: manually test by setting both display and text largest size and
start enrolling fingerprint; the description is hidden if it's too long.
