Convert AccountViewHolder from Java to Kotlin (#3044)

* Convert AccountViewHolder from Java to Kotlin

Use view binding in the converted code, which requires small changes in code
that calls constructors.

Pass showBotOverlays as a parameter, rather than having the code reach in to
the shared preferences, fixing a layering violation. This affects callers
and classes derived from AccountAdapter.

* Use 2-arg getString

* Simplify setting bot badge indicator

- Specify the drawable in the XML
- Use visible() to set visibility
- Rename ID to account_bot_badge to make it clearer that this is all it is for

* Use lateinit to avoid needing !! later
