event/octeontx2: add SSO dual workslot mode

OcteonTx2 AP core SSO cache contains two entries each entry caches
state of an single GWS aka event port.
AP core requests events from SSO by using following sequence :
1. Write to SSOW_LF_GWS_OP_GET_WORK
2. Wait for SSO to complete scheduling by polling on SSOW_LF_GWS_TAG[63]
3. SSO notifies core by clearing SSOW_LF_GWS_TAG[63] and if work is
valid SSOW_LF_GWS_WQP is non-zero.
The above sequence uses only one in-core cache entry.

In dual workslot mode we try to use both the in-core cache entries by
triggering GET_WORK on a second workslot as soon as the above sequence
completes. This effectively hides the schedule latency of SSO if there
are enough events with unique flow_tags in-flight.
This mode reserves two SSO GWS lf's for each event port effectively
doubling single core performance.
Dual workslot mode is the default mode of operation in octeontx2.

eventdev: add new software timer adapter

This patch introduces a new version of the event timer adapter software
PMD. In the original design, timer event producer lcores in the primary
and secondary processes enqueued event timers into a ring, and a
service core in the primary process dequeued them and processed them
further.  To improve performance, this version does away with the ring
and lets lcores insert timers directly into timer skiplist data
structures; the service core directly accesses the lists as well, when
looking for timers that have expired.

To compare the burst and non-burst performance of the original and new
versions of the software event timer adapter, I ran the following
commands:

$ sudo ./build/app/dpdk-test-eventdev -c 0xFFE -s 0xC --vdev=event_sw0 \
-- --test=perf_queue --plcores=4,5,6 --wlcore=7,8,9 --stlist=p \
--prod_type_timerdev --worker_deq_depth=32

$ sudo ./build/app/dpdk-test-eventdev -c 0xFFE -s 0xC --vdev=event_sw0 \
-- --test=perf_queue --plcores=4,5,6 --wlcore=7,8,9 --stlist=p \
--prod_type_timerdev_burst --worker_deq_depth=32

With the new version, I see a 151% improvement in throughput for the
non-burst case, and a 270% improvement in throughput for the burst case.
I also see a 53% improvement in arm latency in the non-burst case and a
65% improvement in arm latency in the burst case.

Note: To perform the test,  I commented out a check in the original
version that checks the adapter tick interval against a minimum value.

testing. This patch enables this functionality in the pcap driver.

At a high level, this works by creating a ring of sufficient size to
store the packets in the pcap file passed to the application. When the
rx function for this mode is called, packets are dequeued from the ring
for use by the application and also enqueued back on to the ring to be
"received" again.

A tx_drop mode is also added since transmitting to a tx_pcap file isn't
desirable at a high traffic rate.

Jumbo frames are not supported in this mode. When filling the ring at rx
queue setup time, the presence of multi segment mbufs is checked for.
The PMD will exit on detection of these multi segment mbufs.
