Add c2c and chat support when there is eligible account.

Bug: 28141203
Bug: 28316618
Bug: 28316343

- Replaced hardcoded fragment layout with a RecyclerView. The old layout
  was essentially building a list manually.
- Tweaked layout to look better.
- Hide escalation cards when there is no account. Show cards when
  there is at least 1 account.
- Request an intent to start specified support type when card is
  clicked.
- Monitor account changes so we can hide/show escalation cards when
  add/remove account.
