[MAC rand] DeviceConfigFacade refactor + plumbing

Refactors DeviceConfigFacade to centralize where fields get updated.
And plumbs the flag "aggressive_randomization_per_ssid_enabled" to
control whether the framework will consider using aggressive
randomization per-SSID based on a whitelist appraoch.

Bug: 137795359
Test: unit tests
Test: manually tested on device using "adb shell device_config put wifi
aggressive_randomization_per_ssid_enabled true"
