The patch changes rx_burst profiling approach:
1. VTune's instrumentation is removed
2. empty hook callback for profiling is added
This way all VTune-specific logic moves to the VTune side.
Hook is enabled only when CONFIG_RTE_ETHDEV_PROFILE_WITH_VTUNE o

The patch adds tracing of loop iterations that yielded no packets in a DPDK
application. It is using ITT task API:
https://software.intel.com/en-us/node/544206
We suppose the flow of using this tracing would assume the user has ITT lib
and header on machine and re-build
