eventdev/dma: reorganize event DMA ops
Re-organize event DMA ops structure to allow holding
source and destination pointers without the need for
additional memory, the mempool allocating memory for
rte_event_dma_adapter_ops can size the structure to
accommodate all the needed source and destination
pointers.
Add multiple words for holding user metadata, adapter
implementation specific metadata and event metadata.

-----------Note---------
Based on dpdk24.07-rc2 which includes
https://bugs.dpdk.org/show_bug.cgi?id=3D1469's fix patch, also test hang.
Please confirm it need fix or not on ABI compatibility testing or it needn't
test for ABI compatibility testing. Thanks.
