What is the purpose of this pull request?

The sort-keys autofix previously used a pairwise swap strategy, where each --fix pass only swapped two adjacent out-of-order members. For a fully reversed object with N keys, this required up to N-1 passes of eslint --fix to reach a fully sorted state.

What changes did you make? (Give an overview)

I replaced the pairwise swap fixer with a segment-based sorting approach that fully sorts all keys in a single pass.

Not stale. I just forgot this was a draft.

This PR has too many unnecessary unrelated changes to making the fix sort in a single pass.
Can you please limit the changes to the context.fix method as there is no need to precompute the fixes if there are none (which should be vast majority of cases)?
You can just use break after reporting to only report once.

Note that @humanwhocodes/momoa doesn't include comments in the object.members tree, so we can't just see if a member is preceded by a comment
You can use sourceCode.getTokenBefore(property, { includeComents: true }) for this.

Note for other reviewers: This would change the current behavior of reporting every unsorted key but only fixing the first group (because of the break after the context.report). I think this behavior is okay as the other groups will be fixed in subsequent rounds. The alternative would be to group everything and do the fixes for every group.

Thank you for refactoring this, I only have some small notes.
