Switch to recyclerview in ManageApplications

- Replace ListView with RecyclerView in layout - Replace ApplicationAdapter's superclass to be RecyclerView.Adapter - Change adapter interfaces (where necessary) to work with RecyclerView - Replace fast scroll with Recycler's mechanism (all in xml) - Removed section indexer (text bubble when fast scroll) because recyclerview doesn't support it. Bug: 64804294 Test: robotests Change-Id: I55b221836ce6abdeddf4568c8a8a5632cbddbd3b
