wifi: ath12k: Move DP specific link stats to DP link peer

Browse source 
As part of peer modularization in the Driver Framework, the station view is as
follows:

            Common Path                      Data Path
    -------------------------------------------------------------------
    ath12k_sta                           ath12k_dp_peer
        |                                       |
        |-> ath12k_link_sta    <---->           |-> ath12k_dp_link_peer
        |                                       |
        |-> ath12k_link_sta    <---->           |-> ath12k_dp_link_peer
        |                                       |
        |-> ath12k_link_sta    <---->           |-> ath12k_dp_link_peer

Currently ath12k_link_sta has data path stats updated in tx_htt and rx monitor
path. Move those stats from ath12_link_sta to ath12k_dp_link_peer to align with
peer modularization model as shown above.

This allows datapath to use only ath12k_dp_link_peer without having to reach out
to other objects for updating stats, thereby improving the cache locality.

Add following API to fetch rate info from DP link peer:

	ath12k_dp_link_peer_get_sta_rate_info_stats()

This wrapper API populates link stats in 'struct ath12k_dp_link_peer_rate_info',
which can be extended to support out-of-band retrieval of various rate stats.
