Simon Lin 00f3043a06 [mlr] send MLR.req for local multicast addresses (#5248) 
This commit includes:

- Adding compile configurations necessary for MLR features
- Adding source/header files necessary for MLR features
- Send MLR.req for local MAs on ThreadNetif
  - At most one MLR.req is outstanding
  - Reregistration according to PBBR configuration
  - Renewing periods according to PBBR configuration
- BBRs receive MLR.req with minimal processing and send MLR.rsp
- Add a test to verify that MLR.req is sent for local MAs.
