Subject: [PATCH] Display "pair new" only when local output device is
 available.

-If media app does not support cast->phone transferring, local output
audio device is unavailable. "pair new" is for Bluetooth which should be
also unavilable.
-These types are local output audio devices:
TYPE_BUILTIN_SPEAKER
TYPE_WIRED_HEADSET
TYPE_WIRED_HEADPHONES
TYPE_USB_DEVICE
TYPE_USB_HEADSET
TYPE_USB_ACCESSORY
TYPE_DOCK
TYPE_HDMI

Bug: 163095048
Test: make -j50 RunSettingsRoboTests
Change-Id: Ib844c7546e1946cb87fac04cb8b2b8f4acf06451
(cherry picked from commit 113ac8102aa1db6a1d901e6acbd41ca8f9cb934d)
