WifiStack: Expose all wifi resources to be overlayed

All of the wifi resources have been added to overlayable.xml. So, OEMs
can customize all the wifi config values.

Also, added a sample overlay app to demonstrate how OEMs can customize
these overlayable configs.

Bug: 143464763
Test: Verified that the sample overlay app can override configs.
