env_dpdk: add required APIs to handle interrupt 



Add the necessary interfaces to create and delete eventfds, and to fetch
it for a particular index. These are required to enable and disable
multiple interrupts for pcie nvme devices.
As only VFIO MSIX supports multiple interrupt vectors, added an
interface to check the same.
