Update UI for account switcher

The text is updated to include the app name.
(strings will be updated following go/android-late-strings)

The personal profile icon is tinted with the same
color as the work badge (blue).

Tints are set using setColorFilter(...) so that they
are not overridden by callers using setTint.
