Proposal: Move towards a Kotlin Multiplatform project

[oxisto]

We should discuss whether (at some point in the future) we want to move towards a Kotlin Multiplatform project, more specifically to support Kotlin native to generate a native binary instead/or next to a JVM one. This would for example make integration of other libraries/tooling, such as LLVM, go/ or c-based libraries much easier.

In order to do so we probably first need to identity the set of libraries that are pure Java (and get rid of them), ideally replacing them with Kotlin libraries that already have Multiplatform support.

Dependencies

• Replace log4j
• Get rid of all places that use Java reflections directly (slightly blocked by https://youtrack.jetbrains.com/issue/KT-32198)
• Moving from Eclipse CDT to tree-sitter #608
