CI: Merge kernel-ark with linux-next

This creates a new CI job to regularly merge the kernel-ark tree with linux-next. The primary goal is to proactively identify integration issues, conflicts and bugs before they land in the main os-build branch.

This initial version is a proof-of-concept and includes logic for automatically resolving merge conflicts using AI. While it successfully handles reported configuration mismatches by adding them to a pending directory, it doesn't yet address misconfigured options or analyze the reasons behind these config issues. This serves as a foundation for building more sophisticated automation to help resolve these types of problems in the future.

This also introduces the dist-configs-commit-mismatches make target to resolve config mismatches.
