feat: Introduce a build push --output option

which controls where the build result is exported.

The default value is "registry" to reflect the current behavior of
`build push`.

Any value provided to this option will be passed to the `buildx build`
command as a `--output=type=<VALUE>` flag.

For example, the following command will push to the local docker image
store:

    kamal build push --output=docker
