supplicant(interface): Add support for DRIVER commands

These were legacy commands added to wpa_supplicant specifically for
android when the vendor HAL did not exist. These string commands are
passed as passthough to the driver by wpa_supplicant. Instead of adding
a single method to pass through these strings. Add separate methods for
each "DRIVER xxx" command that we currently used in Android framework.
