Reformat Kotlin code (#1560)

ktfmt has much improved how it formats Kotlin code. Unfortunately, this
means that whenever we touch a single line in a Kotlin file, we get a
_lot_ more changes thanks to ratcheting now picking up this file for
formatting.

This PR just reformats every single Kotlin file so we don't have to deal
with this churn in future PRs that touch Kotlin code.
