Simplify app prediction service check

In support of sharesheet unbundling:

This change removes the use of the passed in boolean flag to
determine AppPredictionService availability and instead falls
back checking for a non null value from
PackageManager#getAppPredictionServicePackage()

This PackageManager call can now be made directly from outside
of system_server, enabling progress towards sharesheet unbundling.

Bug: 220895016
Test: Enable unbundled sharesheet; share app content; observe share targets
