This commit adds support for independent enqueue feature
and updates Event Device and PMD feature list.
A new capability RTE_EVENT_DEV_CAP_INDEPENDENT_ENQ is introduced
to support independent enqueue to support PMD to enqueue in any order
even the underlined hardware device needs enqueues in a strict dequeue
order.
To use this capability applications need to set flag
RTE_EVENT_PORT_CFG_INDEPENDENT_ENQ during port setup only if the
capability RTE_EVENT_DEV_CAP_INDEPENDENT_ENQ exists.
