wifi: ath12k: Refactor REO command to use ath12k_dp_rx_tid_rxq
Introduce ath12k_dp_rx_tid_rxq as a lightweight structure to represent
only the necessary fields for REO command construction. Replace direct
usage of ath12k_dp_rx_tid in REO command paths with this new structure.
This decouples REO command logic from internal TID state representation,
improves modularity, and reduces unnecessary data dependencies.
