qcacld-3.0: Enable packet tracker for non performance builds

Enable the packet tracker feature for non performance builds
by enabling the macro QCA_PKT_PROTO_TRACE and set the
default packet tracker log level to dump the DHCP, EAPOL
and management packet details. The necessary log level can
be modified using the ini 'gEnableDebugLog' entry either at
compile time or at run time using the IOCTL 'setDbgLvl'.
The logs are dumped using the same IOCTL 'setDbgLvl'.

e.g.,
To enable all the packet trace features
- iwpriv wlan0 setDbgLvl 0x0f
To dump the packet trace
- iwpriv wlan0 setDbgLvl 9999
