Epic: Implement manifests for Podman Desktop

[cdrage]

Epic domain

Within Podman Desktop, it would be beneficial to do the equivalent to the Podman CLI:

# First, initialise the manifest
podman manifest create <image name>

# Build the image attaching them to the manifest
podman build --platform linux/amd64,linux/arm64  --manifest <image name>  .

# Finally publish the manifest
podman manifest push <image name>

In order to create a multi-platform / multi-arch singular image.

Implementation tasks (in order):

• [ ] Add manifest API to Podman Desktop https://github.com/containers/podman-desktop/issues/6527
• [ ] Be able to create a multi-platform / multi-arch manifest from within the UI on the "Build Image" screen https://github.com/containers/podman-desktop/issues/6236
• [ ] Be able to view / see details of manifest on image page https://github.com/containers/podman-desktop/issues/6529
• [ ] Add functions such as push manifest, rename manifest, etc similar to image actions. https://github.com/containers/podman-desktop/issues/7041
