Subject: [PATCH] Add a static method on the ApplicationsState to enable app
 icon cache

This will be used by the EBS (Flipendo) process to enable the app icon cache mechanism to improve the resume latency without loading the icon from the PackageManager again

Bug: 232360114
Test: presubmit and local verification on the EBS page
