1. Add mpp_rc_api and mpp_rc_defs for open rc module to external users.
2. Add RcImplApi registration and setup function.
3. Separate RC module from the encoder implement.
4. Use EncFrmStatus and EncRcTaskInfo to control work flow.
5. proc_rc and update_rc function in enc_impl are removed.
6. Use rc_frm_start and rc_hal_start to process rate control.
7. Add more RcCfg setup in mpp_enc_v2.cpp.
