libandroidfw hardening for IncFs
...
Migrate libandroifw to using incfs::util::map_ptr to prevent processes
from crashing when parsing the resources.arsc, parsing compiled xml,
files, and retrieving resource values.
This change propagates incremental failures to the JNI level where they
are raised as ResourcesNotFoundException.

Fix GetResourceName for shared libraries
...
GetResourceName used GetPAckageById which only works when the compile
time package id is eqal to the runtime package id. This change resolves
resource names correctly using the ruuntime package id.
Bug: 79666085

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
