selftests: mlxsw: Add a test for VxLAN configuration with a VLAN-aware bridge 



Extend the existing VLAN-unaware tests with their VLAN-aware
counterparts. This includes sanitization of invalid configuration and
offload indication on the local route performing decapsulation and the
FDB entries perform encapsulation.
