3925: Implement assist "Reorder field names" r=matklad a=geoffreycopin

This PR implements the "Reorder record fields" assist as discussed in issue #3821 .

Adding a `RecordFieldPat` variant to the `Pat` enum seemed like the easiest way to handle the `RecordPat` children as a single sequence of elements, maybe there is a better way ?
