Don't require BROWSABLE

Initially we wanted to limit instant apps to VIEW/BROWSABLE
intents, but, apparently apps don't always set the BROWSABLE
category. So, allow any VIEW intent w/ a URL to resovle to
an instant app.

Change-Id: I96e25cca8abcbe89b4a227b707112184c19565c6
Fixes: 38146110
Test: Manual
Test: open go/aia-test-links
Test: click any link
Test: notice it launches the instant app directly [instead of going through the installer]
