For the Intent ACTION_SETTINGS_LARGE_SCREEN_DEEP_LINK,
EXTRA_SETTINGS_LARGE_SCREEN_DEEP_LINK_PENDING_INTENT is for partner
apps to tell target Activity the private Activity to start.
However, developers feedback that customization extra data are
preferred, so a later CL supports customized extra data for
ACTION_SETTINGS_LARGE_SCREEN_DEEP_LINK.
Developers will not need
EXTRA_SETTINGS_LARGE_SCREEN_DEEP_LINK_PENDING_INTENT to specify
a private Activity.
