selftests: forwarding: Add bridge MDB test 

Add a selftests that includes the following test cases:

1. Configuration tests. Both valid and invalid configurations are
   tested across all entry types (e.g., L2, IPv4).

2. Forwarding tests. Both host and port group entries are tested across
   all entry types.

3. Interaction between user installed MDB entries and IGMP / MLD control
   packets.

Example output:
