ApexManager: Post populateAllPackagesCacheIfNeeded to a background thread
populateAllPackagesCacheIfNeeded is rather expensive method and
shouldn't be run in broadcast handler thread (it was my mistake to
suggest this in ag/9204784).
It's fine to use background thread to execute
populateAllPackagesCacheIfNeeded because components that need
to match APEX are not doing it on user critical path.
