Pull request overview
This PR updates the build system to differentiate between host and guest artifacts, enabling developers to build artifacts for their local platform by default while maintaining support for guest (Linux) artifacts.
Key changes:
- Introduced
HOST_OSvariable and platform-specific build targets (_host_common,_guest_common) - Modified the default build group to include separate host and guest binary groups
- Updated the Makefile to detect and use the local platform for builds

The libkrun target is missing an inherits declaration. Since it's part of the guest-binaries group (line 77), it should inherit from _guest_common to ensure consistent platform targeting.

Variable naming inconsistency: KERNEL_ARCH is used here but TARGETARCH is the standard Docker build argument. Consider renaming to HOST_ARCH for consistency with HOST_OS, or document why a different convention is used.

I need to check this config. Putting this into draft.

This change updates the build to split artifacts into host/guest. By default, build the host artifacts to match the developers local platform.
