qcacmn: Add Support for ACTION_CATEGORY_RVS

Currently, mgmt_txrx_get_action_frm_subtype does not handle
ACTION_CATEGORY_RVS. In case action_category is
ACTION_CATEGORY_RVS, mgmt_txrx_get_action_frm_subtype
returns MGMT_FRM_UNSPECIFIED due to default handling. Function
tgt_mgmt_txrx_rx_frame_handler returns QDF_STATUS_E_FAILURE
on receiving MGMT_FRM_UNSPECIFIED frame type and drops mgmt
frames.

Fix is to add support for ACTION_CATEGORY_RVS in
mgmt_txrx_get_action_frm_subtype to avoid drop of MCSC
frames. Add new management frames MGMT_ACTION_SCS_REQ,
MGMT_ACTION_SCS_RSP, MGMT_ACTION_GROUP_MEMBERSHIP_REQ,
MGMT_ACTION_GROUP_MEMBERSHIP_RSP, MGMT_ACTION_MCSC_REQ,
MGMT_ACTION_MCSC_RSP and new element ACTION_CATEGORY_RVS
in mgmt_action_category. mgmt_txrx_get_action_frm_subtype
Finds rvs frame subtype and returns subtype instead of returning
MGMT_FRM_UNSPECIFIED.
