This adds a bit mask of driver_info for Microsoft vendor extension and indicates the support for Intel 9460/9560 and 9160/9260. See https://docs.microsoft.com/en-us/windows-hardware/drivers/bluetooth/ microsoft-defined-bluetooth-hci-commands-and-events for more information about the extension. This was verified with Intel ThunderPeak BT controller where msft_vnd_ext_opcode is 0xFC1E.
