wifi: ath12k: Refactor macros to use memory profile-based values

Refactor macros to compute values dynamically at runtime based on the
ath12k_mem_profile_based_param structure.

Remove hardcoded logic to allow driver to operate more efficiently in
memory-constrained platforms without significant functional impact.
