Add volume prune --filter support

This change adds support for the `--filter` / `?filters` arguments on
the `podman volume prune` subcommand.

  * Adds ParseFilterArgumentsIntoFilters helper for consistent
    Filter string slice handling
  * Adds `--filter` support to podman volume prune cli
  * Adds `?filters...` support to podman volume prune api
  * Updates apiv2 / e2e tests

Closes #8672
