wifi: ath12k: introduce host_alloc_ml_id hardware parameter

Different ath12k devices diverge on who allocates MLD peer id:
WCN7850/QCC2072 have the firmware allocate it and notify the host via
HTT_T2H_MSG_TYPE_MLO_RX_PEER_MAP event; While others let the host allocate
it and pass it down through WMI_PEER_ASSOC_CMDID with
ATH12K_WMI_FLAG_MLO_PEER_ID_VALID set.

Currently ath12k host allocates this ID and sends it to firmware by
default for all devices. This breaks WCN7850/QCC2072, because the host
maintained ID may be different from the firmware-allocated one.
Consequently data path may fail to find the dp peer and drop some received
packets. From user point of view, this results in bugs reported in [1] or
the 4-way handshake timeout issue.

Add host_alloc_ml_id flag to struct ath12k_hw_params (and a copy on struct
ath12k_hw for hot-path access) so subsequent patches can branch on it. Set
true for QCN9274/IPQ5332/IPQ5424, false for WCN7850/QCC2072. The flag will
be consumed by subsequent patches.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00302-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.115823.3
