Bluetooth: btintel: Enable extra Intel vendor events

Browse Source 
The Intel Bluetooth controllers can emit extra vendor specific events in
error conditions or for debugging purposes. To make the life easier for
engineers, enable them by default. When the vendor_diag options has been
enabled, then additional debug events are also enabled.
