Bug 40016: Allow inheriting from AddonCollectionProvider

This will allow implementing our own AddonsProvider in fenix.

This matches the search engines from desktop, that is:
DDG as the default, then YouTube, Google, DDGOnion,
Startpage, Twitter, Wikipedia and Yahoo.

Together with the corresponding fenix patch, this allows all `startActivity`
that may open external apps to be replaced by `TorUtils.startActivityPrompt`.
