Add ActivityOptions.displayId when launching home intent.

When we launch home intents, either primary or secondary, we also must
supply a displayId, or else Core will end up launching all home launcher
types on the default display (e.g. launching secondary_launcher on
primary display/moving it, which is not wanted).
