build: allow using cache explicitly with --squash-all using --layers
Buildah already supports using `--layers` with `--squash` after https://github.com/containers/buildah/pull/3674
if user wants to do so hence podman must honor similar configuration
in `--squash-all` behaviour if user wants to using cache.
PS: We cannot alter behaviour of `podman build --squash` for
docker-compat reasons hence this feature can be easily supported by
`--squash-all`.
Closes: https://github.com/containers/buildah/issues/4011
