Rename LoginBox to AuthButtons

This component displays login and register buttons. It's currently used in the
composer when viewing a room as a guest.

The name is confusing because the login flow uses are very similarly named
`mx_Login_box` as a wrapping around forms, which is totally different than these
buttons.

Additionally, the components is moved to `views/auth` since it is very simple
and auth related.
