[MAC rand] Removing persistent storage

Will now calculate the randomized MAC address directly for new wifi
networks.
For existing networks that already have saved randomized MAC address, we
will continue to use the saved MAC.

Bug: 140065828
Test: unit tests before and after factory reset
Test: Verified that new MAC address entries are not populated into
WifiConfigStore.xml
Test: Manually verified calculated MAC addresses are consistent and
valid.
Test: Manually verified upgrade path from Q to R to make sure randomized
MAC stays the same.
