cros: Rename lock_screen.mojom to login_screen.mojom

lock_screen.mojom was primarily used for interfacing with ash/login,
which (will) contain the login, lock, and user-add UI. It is not really
ideal to name this all "login" since it is more than login, but that has
been what we've been using thus far.

Alternative names:
- ash/authentication
- ash/entry
- ash/session
- ash/session_entry
