wifi(implementation): Add iface combo for 2018
Changes in the CL:
a) Added iface combo for 2018 using a new feature flag.
b) Added a generic algorithm to determine if an iface can be created or
not based on the iface combos supported. This is needed because we now
have to support 3 different combos (2016, 2017, 2018) in the HAL.
The current iface creation logic is hard to adapt to these 3 varying combos.
