Add config_supportBluetoothPersistedState. 

Add a config to indicate whether a device supports Bluetooth persisted
state and defaulted to true. In ARC++, Bluetooth adapter state can be
out-of-sync from its container if the user changes it before the
container being available.

When set to false, this config prevents Android to auto start the
Bluetooth. ARC++ will set this to false and sync Bluetooth state later
with Android.

Bug: 62413625, 69965109
Test: On sailfish, Bluetooth on/off correctly and state persisted across reboot
