Use service cores for offloading event scheduling in case of
centralized scheduling instead of calling the schedule api directly.
This removes the dependency on dedicated scheduler core specified by
giving command line option --slcore.

With the current scheme of event queue configuration the cfg schedule
type macros (RTE_EVENT_QUEUE_CFG_*_ONLY) are inconsistent with the
event schedule type (RTE_SCHED_TYPE_*) this requires unnecessary
conversion between the fastpath and slowpath API's while scheduling
events or configuring event queues.
This patch aims to fix such inconsistency by using event schedule
types (RTE_SCHED_TYPE_*) for event queue configuration.
This patch also fixes example/eventdev_pipeline_sw_pmd as it doesn't
convert RTE_EVENT_QUEUE_CFG_*_ONLY to RTE_SCHED_TYPE_* which leads to
improper events being enqueued to the eventdev.

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

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 perf queue test configures the eventdev with Q queues and P ports,
where Q is nb_producers * nb_stages and P is nb_workers + nb_producers.
The user can choose the number of workers, the number of producers and
number of stages through the --wlcores , --plcores and the --stlist
application command line arguments respectively.
The producer(s) injects the events to eventdev based the
first stage sched type list requested by the user through --stlist
the command line argument.
Based on the number of stages to process(selected through --stlist),
the application forwards the event to next upstream queue and
terminates when it reaches the last stage in the pipeline.
On event termination, application increments the number events
processed and print periodically in one second to get the
number of events processed in one second.
When --fwd_latency command line option selected, the application
inserts the timestamp in the event on the first stage and then
on termination, it updates the number of cycles to forward
a packet. The application uses this value to compute the average
latency to a forward packet.
Example command to run perf queue test:
sudo build/app/dpdk-test-eventdev --vdev=event_sw0 -- --test=perf_queue\
--slcore=1 --plcores=2 --wlcore=3 --stlist=p --nb_pkts=1000000000

This test verifies the same aspects of order_queue test,
The difference is the number of queues used, this test
operates on a single "all types queue"(atq) instead of two
different queues for ordered and atomic.

The order queue test configures the eventdev with two queues
and an event producer to inject the events to q0(ordered) queue.
Both q0(ordered) and q1(atomic) are linked to all the workers.
The event producer maintains a sequence number per flow and
injects the events to the ordered queue.
The worker receives the events from ordered queue and
forwards to atomic queue. Since the events from an ordered queue can
be processed in parallel on the different workers, the
ingress order of events might have changed on the downsteam
atomic queue enqueue. On enqueue to the atomic queue, the eventdev PMD
driver reorders the event to the original ingress order
i.e producer ingress order).
When the event is dequeued from the atomic queue by the worker,
this test verifies the expected
sequence number of associated event per flow by comparing
the free running expected sequence number per flow.
Example command to run order queue test:
sudo build/app/dpdk-test-eventdev --vdev=event_sw0 --\
--test=order_queue --plcores 1 --wlcores 2,3
