app/testeventdev: add perf all types queue test

This is a performance test case that aims at testing the following:
1. Measure the number of events can be processed in a second.
2. Measure the latency to forward an event.

The atq queue test functions as same as "perf_queue" test.
The difference is, it uses, "all type queue" scheme instead of separate
queues for each stage and thus reduces the number of queues required to
realize the use case and enables flow pinning as the event does not
move to the next queue.

Example command to run perf "all types queue" test:

sudo build/app/dpdk-test-eventdev --vdev=event_octeontx --\
--test=perf_atq --plcores=2 --wlcore=3 --stlist=p --nb_pkts=1000000000
