Wifi: Optionally avoid interface down/up when doing setMacAddress

Some vendors implementation will reset wifi chip when doing interface
down.
Accordingly, We need to avoid the interface down/up when doing
setMacAddress to avoid loss of sync between framework and firmware.

This commit uses a BOARD_WIFI_AVOID_IFACE_RESET_MAC_CHANGE macro to
check if it is needed to avoid interface down/up at setMacAddress.
