Create `container_engines` configs in `falco.yaml`

Motivation

See https://github.com/falcosecurity/falco/issues/3243#issuecomment-2174224867 and additional comments after that comment.

The current favorite seems to expose new container_engines in the following format:

container_engines:
    docker:
      enabled: true
    cri:
      enabled: true
      cri: ["/run/containerd/containerd.sock", "/run/crio/crio.sock", "/run/k3s/containerd/containerd.sock"]
      disable-cri-async: false

This feature will allow end users to explicitly disable some container engines, plus it can help in deployment scenarios where the existing --cri and --disable-cri-async CLI flags are more difficult to configure.
