Add QCA vendor interface to support per-MLO link configurations

Add support for per-MLO link configurations in
QCA_NL80211_VENDOR_SUBCMD_SET_WIFI_CONFIGURATION and
QCA_NL80211_VENDOR_SUBCMD_GET_WIFI_CONFIGURATION commands.

Additionally, add documentation for
QCA_NL80211_VENDOR_SUBCMD_SET_WIFI_CONFIGURATION and
QCA_NL80211_VENDOR_SUBCMD_GET_WIFI_CONFIGURATION commands.
