eventdev: add element offset to event vector

Browse Source 
Add `rte_event_vector:elem_offset:12` bit field event vector
structure the bits are taken from `rte_event_vector::rsvd:15`.
The element offset defines the offset into the vector array
at which valid elements start.

The valid elements count will be equal to
`rte_event_vector::nb_elem`.

Update Rx/Tx adapter SW implementation to use elem_offset.
