qcacld-3.0: Add support to send rate information for mgmt frames

Add support to send rate information for mgmt frames.

Currently default rates are used by target for the mgmt frames before
association. If the AP does not support the default rates (1 Mbps for
2.4G and 6Mbps for 5G), STA would still send AUTH, ASSOC frames with
the default rates. Add support to send the minimum rate supported by
the AP as part of the MGMT Tx WMI command.
