qcacmn: Add QCA vendor attribute for configuring max A-MPDU aggregation count

Add a QCA vendor attribute QCA_WLAN_VENDOR_ATTR_CONFIG_PEER_AMPDU_CNT to
enable configuration of TX maximum aggregate size with a specific peer.
This can be used to improve performance in noisy environment. In AP
mode, the peer MAC address of the associated STA is specified with
QCA_WLAN_VENDOR_ATTR_CONFIG_PEER_MAC.
