Add support for loading images directly from machine paths to avoid
unnecessary file transfers when the image archive is already accessible
on the running machine through mounted directories.
Changes include:
- New /libpod/local/images/load API endpoint for direct machine loading
- Machine detection and path mapping functionality
- Fallback in tunnel mode to try optimized loading first
This optimization significantly speeds up image loading operations
when working with remote Podman machines by eliminating redundant
file transfers for already-accessible image archives.
