[Android] Import tests from SyncAndServicesSettingsTest to GoogleServicesSettingsTest

If MOBILE_IDENTITY_CONSISTENCY is on sections related to autofill
assistant, safe browsing and metrics settings is moved from
SyncAndServicesSettings to GoogleServicesSettings page.

This cl imports tests regarding autofill assistant, safe browsing and
metrics settings to GoogleServicesSettingsTest as SyncAndServicesSetting
is going to be deprecated in the future. This cl does not add any new
tests.
