Move AddToHomescreen to MVC (Part 3)

This is the third part in a series of CLs for moving the
AddToHomescreen component to MVC in Android.

In this CL the AddToHomescreenInstaller and
AddToHomescreenParams classes are added.
AppBannerUiDelegateAndroid and AddToHomescreenManager classes are
edited to use these new classes.

Design doc: http://go/a2hs-mvc

A subsequient CL will implement the coordinator and the mediator classes
and remove the AppBannerUiDelegateAndroid and AddToHomescreenManager
classes.
