[K2] Migrate to new Standalone Analysis API

[vmishenev]

This issue is a requirement for

• [K2] Stabilize pure Kotlin/JVM and mixed Kotlin/Java projects #3140

---

It depends on KT-60884
The current Standalone API is a prototype. It doesn't allow to migrate to compiler 1.9.20 due to the impossibility of creating GlobalSearchScope (contentScope.).

Also, it should unmute tests using JDK.

Background

There are tools and libraries that need to work with Kotlin source code, be it for analysis, modifications or something else. Among examples are Dokka, KSP and IDEs. However, different tools need different levels of information and capabilities, as some might be more sophisticated (IDEs), while others only require the basic information (Dokka, KSP).

The Standalone Analysis API is a very fast, lightweight alternative to the heavy API for IDEs, which should work nicely with Dokka. The Standalone API should also be more stable as it is more generic and has more 3rd party clients than the IDE APIs, which can help Dokka with stability issues.

Issue discussion summary:

We are blocked by KT-60884, because without it we cannot configure the user projects fully and correctly:

• There are problems with setting up JDKs: at the moment JDK 8 is not supported, but it works with JDK 11 for some reason.
• Projects that have external JVM dependencies (i.e they use 3rd party libraries) are not guaranteed to work correctly - some do, some don't.

If put in perspective, it is similar to environment configuration in K1 analysis, which uses a combination of compiler and IDE settings. The Standalone API should replace all of it in K2.

Estimated time of implementing this issue: ~2 weeks
