qcacmn: Add QCA vendor cmd for setting BT coex chain mode

To config BT coex chain mode, add a new QCA sub command
QCA_NL80211_VENDOR_SUBCMD_BTC_CHAIN_MODE.

This new command has two attributes:
1. QCA_VENDOR_ATTR_COEX_BTC_CHAIN_MODE: u32 attribute. Indicates the
   BT coex chain mode, are 32-bit values from enum qca_btc_chain_mode.
2. QCA_VENDOR_ATTR_COEX_BTC_CHAIN_MODE_RESTART: flag attribute.
   If set, vdev should be restarted once BT coex chain mode is updated.
