Add MacRandomizationSetting to WifiConfiguration 

Allow setting different levels of MAC randomization for each network.
For now, we are going to support "Persistent" which generates randomized
MAC once and persist that MAC, and "Trusted" which uses the factory MAC.

Bug: 118396042
Test: Existing unittest verifying parcel
Test: adb shell dumpsys wifi | grep -B8 "MacRandomizationSetting"
