Record data about dex files use on disk
Add DexManager to keep track of how dex files are used.
Every time a dex file is loaded, PackageManager will notify DexManager
which will process the load. The DexManager will look up what package
owns the dex file and record its use in package-dex-usage.list (through
PackageDexUsage).
Test: device boots, package-dex-usage.list is created and contains valid data, after device reboot the list is succesfully read from disk.
