Launch ephemeral intent

In MR1, the ephemeral application was launched via the supervisor.
In O, the ephemeral application is installed on the system as a
proper application and runs natively.

Bug: 30204367
Test: build & install the framework and run 'adb shell am start -a android.intent.action.VIEW -c android.intent.category.BROWSABLE -d "https://www.tripadvisor.com/Tourism-g33020-San_Jose_California-Vacations.html"'
