Reduce RM createResources lock contention
Reduce lock contention for processes that use
ResourcesManager#createResources on background threads by preloading
the apk assets into a temporary cache while the RM lock is not held.
As a result, multiple threads may be performing I/O opening the same
apk assets since multiple threads could be preloading the same apk
at once.
Bug: 111966000
Test: observe significantly less monitor contention with owner bg
threads calling android.app.ResourcesManager.createResources
