Build AppsFilter cache in background
This change attempts to update the apps filter cache in the background
and without holding the package manager lock. It makes a local copy of
the package settings and gets the hashcode of each setting's package
object. After building the cache, it checks that all of the packages are
the same as before the cache was built. If there was a change, the cache
is discarded and rebuilt while holding the package lock.
