Android TV launcher and lock task fixes

Add a launcher intent filter for Android TV.
Use the LEANBACK_LAUNCHER category instead of the LAUNCHER category when creating launcher intents on Android TV.
When starting apps from the kiosk mode activity use getLeanbackLaunchIntentForPackage instead of getLaunchIntentForPackage when running on Android TV.
