changesets

- Minor revision of wording from original changeset in 8af45cd
- That wording is now associated with a changeset specific to `@getodk/xforms-engine`, where that language will probably make more sense
- A more terse changeset is also added for `@getodk/xpath`, only describing the nature of the change for that package

+The `xf:distance` XPath function now accepts multiple arguments. This makes it easier to compute the distance between multiple points within a form's primary instance. Previously, to achieve this, you'd have to introduce a `calculate` which concatenates those points together, then call the distance function with a reference to that `calculate` as the argument.
