wifi: ath12k: Add a table of parameters entries impacting memory consumption

Browse Source 
Introduce ath12k_mem_profile_based_param structure to define
configuration parameters for both default and low-memory profiles.

Add support for enabling the low-memory profile in the follow-up
patch by making the following changes:
- Reduce sizes for transmit, receive, and monitor descriptor rings.
- Reduce transmit and receive descriptor count.
- Limit the maximum number of virtual devices (vdevs) to 9.
- Reduce the maximum number of client support per radio.

Centralize these parameters in the ath12k_mem_profile_based_param
structure to simplify switching between memory profiles.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.5-01651-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 WLAN.HMT.1.1.c5-00284.1-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
