RFE: support OCI with --force-compression --compress=false

[dougsland]

Today the --force-compression and --compress=false only works with dir: and not oci:.

Here an example of command:

podman push --force-compression --compress=false  docker.io/nginx:1.24.0 dir:/tmp/tmpdirtest

/cc @mtrmac @giuseppe

Uh, I don’t know what --force-compression + --compress=false is supposed to do. --force-compression only makes any difference when --compression-format is specified.

Either way, c/image does give callers the choice with oci: destinations, via SystemContext.OCIAcceptUncompressedLayers; whether Podman’s CLI option activates that or not (incompatibly changes the semantics of an existing option, to be pedantic, though I could see a reasonable argument to do that), is a Podman decision.
