Integrate CP2 Android B Default Account APIs

Sdk 36 introduced new APIs for managing the default account for new
contacts that change the behavior of CP2 when certain default accounts
are set,
https://developer.android.com/identity/providers/contacts-provider/contacts-storage-locations?hl=en.

The app now delegates to the default account picker in CP2 whenever the
user would have been prompted to set a default account, e.g. when
inserting without a default or through app settings.

Since CP2 does not allow new contacts in local accounts when the
default account is set to a cloud, the app hides these accounts
during insert flows.
