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.
