wifi: ath12k: Enable AST index based address search in Station Mode

Browse Source 
Currently, TCL performs the TX address search for each entry during
transmission, which may lead to packet delays.

To mitigate this issue, enable AST index-based address search during
transmission in station mode. This AST index-based search is not
enabled in AP mode due to the complexity involved in fetching peer
information.

Implement changes to retrieve the offset of ast_idx/ast_hash values
from the PEER_MAP3 event, update the vdev search type to ADDRX, and
enable AST lookup in the bank configuration.
