[Android Settings] Use dropdown value for content description

Currently, when editing dropdown values on settings pages (e.g., adding
an address to Autofill), the accessible description is just the name of
the field (e.g., if a Country dropdown is set to "Canada", the screen
reader will announce "Country" instead of "Canada"). This CL sets the
description properly.
