Update Dialer UI to prompt for permissions

First pass at adding functionality to Dialer to prompt for
permissions. Also updates the UI for various fragments when
there are no contacts/calls available to unify the UI with the
new UI for the permissions denied state.

* Refactor existing empty view functionality and encapsulate
into a new custom view class

* Add action buttons to existing empty views in various fragments
-> Speed Dial (Add to favorites) - scrolls to all contacts fragment
-> Recents (Make a call) - shows dialpad
-> All contacts (Add a contact) - Launches add contact dialog

* Add functionality to various fragments to detect if permissions
are denied, and request the permission when the action button
is pressed.
-> Speed Dial (request for contacts permission)
-> Call Log (request for phone permission)
-> All contacts (request for contacts permission)

* Remove now unneeded EmptyContactsListAdapter

Remaining issues (to be addressed in a follow up CL to avoid bloating
this CL):
UI alignment tweaks for empty view to match mocks
If the read contacts permission is requested from the
speed dial screen, the all contacts fragment doesn't update with
the list of contacts until restarted.
