added in the three roles: search, adjustable, link that require localization 

Summary:
Added the android functionality for those three roles: search, adjustable, and link.
Until React Native internal framework ports internationalization and localization of strings, I'll handle localization by allowing an extra prop to be passed in that can override talkback's description in another language if needed.
