k8s-1.30: Enable feature-gate of DRA alpha feature

This is related to ongoing projects to test Dynamic Resource
Allocation (DRA) in KubeVirt:

    https://kubernetes.io/docs/concepts/scheduling-eviction/dynamic-resource-allocation/

I'm enabling it in k8s-1.30 as per ongoing PCI passthrough driver
developed by Sibasish Behera as part of his GSoC 2024 project, see:

    https://github.com/kubevirt/dra-pci-driver

Based on Alice's patch.
