PackageManagerService: Implement packageParser cache in ParallelPackageParser.
We save about 2800ms of cold startup time over baseline on a marlin,
and ~1200 ms over the parallel parsing case.
warm cold
---------------
Baseline : 1700ms 4300ms
Parallel : 1400ms 2700ms
Cache : 1000ms 1600ms
Cache & parallel : 900ms 1500ms
Note that further changes will improve the speed of cache processing.

- a flag that been flipped in code (currently set to false).
- disabling the cache via a system property.
- wiping the cache on system upgrades.
