Custom runtimes with Kotlin/Native

While [Ktor doesn't support Kotlin/Native yet](https://youtrack.jetbrains.com/issue/KTOR-746) maybe the Kotless DSL can be ported. I do believe it will reduce cold boot times and costs, maybe even functions will run faster. Maybe I can give it a shot in my spare time but first I'd like to hear your thoughts. Are you interested in support for custom runtimes in Kotless? Would you consider merging such a pull request from the community? If so I would love to hear about the preferred approach to tackle this issue.

The issue names no repository files, tests, or entry points. Start by reviewing the linked AWS Lambda, Azure Functions, Alibaba Cloud, and IBM OpenWhisk custom-runtime documentation; completion criteria are not defined because the request awaits agreement on whether and how Kotless should support custom runtimes.
