wifi: ath12k: move HE MCS mapper to a separate function 

Refactor the HE MCS mapper functionality in
ath12k_mac_copy_he_cap() into a new function.

This helps improve readability, extensibility and will be used
when adding support for 160 MHz bandwidth in subsequent patches.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
