Privapp IntentResolver += PACKAGE_USAGE_STATS

This permission is required to query AppPredictionService.

When the unbundled Chooser doesn't request this permission,
we get a SecurityException attempting to invoke
createPredictionSession(). When we request the permission
but don't add it to this allow-list, the device boot-loops.
With the permission added in both places (and some other
local changes), the unbundled Chooser is able to show the
full set of app predictions.

Test: Manual, as described above.
