Add function to return path for last resolved resource
After an AssetManager.FindEntry call is made, either directly or from any of the resource entry calls, a stack of the steps taken to resolve the resource is saved. Those steps can be retrieved as a log later on by calling AssetManager.GetLastResourceResolution, which returns a formatted string of the resource ID/name and path taken, including the configs and package names of each step.
Logging and the saving of the steps to memory can be enabled/disabled with the @hide .setResourceResolutionLoggingEnabled() method on AssetManager.
Bug: 122374289
Test: cases for single and multi ApkAssets loaded
Test: case for no resolution made
Test: made test app to display log on device
Test: added debugging call to source and ran through on-device apps
