2 panes deep link for large screen devices

This change supports deep link to Settings app internal pages
and external pages outside Settings app.

Apps need android.permission.ALLOW_TWO_PANES_DEEP_LINK_IN_SETTINGS
to send the intent of Settings#ACTION_SETTINGS_LARGE_SCREEN_DEEP_LINK.
Settings app will startActivity for the intent from
Settings#EXTRA_SETTINGS_LARGE_SCREEN_DEEP_LINK_INTENT_URI.

Test: build pass
