[Test Setup]
Steps to reproduce
1. Use the following command to build DPDK:
CC=clang meson -Denable_kmods=True -Dlibdir=lib --default-library=static -Dbuildtype=debug -Db_lundef=false -Db_sanitize=address x86_64-native-linuxapp-clang
ninja -C x86_64-native-linuxapp-clang/ -j 70
2. Execute the following command in the dpdk directory. x86_64-native-linuxapp-clang/app/dpdk-fuzz
[Show the output from the previous commands]
~/dpdk# x86_64-native-linuxapp-clang/app/dpdk-fuzz /tmp/fuzz_seed/hash_seed/ -- -ignore_remaining_args=1 -l 1 -n 4 --no-pci

ethdev: add trace points
Adds trace points for ethdev functions.
The rte_ethdev_trace.h is removed. The file ethdev_trace.h is added as an internal header. ethdev_trace.h contains internal slow path and fast path tracepoints. The public fast path tracepoints are present in rte_ethdev_trace_fp.h header.
