[mlr] add MulticastListenersTable on BBR (#5292)

Browse Source 
This commit adds the Multicast Listener Table for BBR:

- Implements Multicast Listener Table on BBR
  - Adds registered MAs to MulticastListenerTable
  - Reject when the table is full or the multicast address is invalid
    and return failed status
  - Respond with unsuccessful status along with failed addresses
  - Expire Listeners from MulticastListenerTable per second (using
    MinHeap for better performance)
- MLR enhancement
  - Re-register only failed multicast addresses (used to register all
    registering multicast addresses)
- Reference Device only APIs
  - Some APIs are defined for reference devices and tests.
- Add tests
  - Add unit test: test_multicast_listener_table.cpp (runs for 1.2-bbr
    only)
  - Add functional tests
