Support OCI VolumeSource

[jimmyjones2]

Feature request

Released as alpha in Kubernetes v1.31 - this allows you to mount OCI images or artefacts as a volume. For tekton, add support for OCI VolumeSource Workspaces.

Use case

When using the trivy vulnerability scanner as part of the pipeline, mount the trivy database (ORAS) as a workapace, benefiting from the local image cache - saving bandwidth and will load faster.

I'm sure they'll be other tasks that require large blobs of data that would also benefit from this feature. The current workaround would be to bake the data into the image itself, but the KEP outlines the downsides of that approach.
