client/mgmt: Add hci-cmd command

Browse Source 
This adds hci-cmd command which uses the MGMT_OP_HCI_CMD_SYNC:

bluetoothctl> mgmt.hci-send 0xffff
bluetoothctl[44]: @ MGMT Com..nd (0x005b) plen 6  {0x0002}
        Opcode: 0xffff
        Event: 0x00
        Timeout: 0 seconds
        Parameters Length: 0
        Parameters[0]:
< HCI Command: Vendor (0x3f|0x03ff) plen 0
> HCI Event: Command Status (0x0f) plen 4
      Vendor (0x3f|0x03ff) ncmd 1
        Status: Unknown HCI Command (0x01)
@ MGMT Event: Command Status (0x0002) plen 3    {0x0002}
      Send HCI command and wait for event (0x005b)
        Status: Failed (0x03)
