[WIP] Kotlin 2.0 support (2.0.0-RC3)

[3flex]

Unless I've missed something it seems that the classic method of running detekt is compatible with K2 but the compiler plugin isn't.

Testing & experimentation is encouraged.

Fixes #6715

Hey @3flex after trying the commit 429a178 as you mentioned here #6715 (comment). I've been able to compile your branch and generate the library on my MavenLocal. But when I've run detekt in my project, I am getting the following errors:

> Task :build-conventions:compileKotlin FAILED
e: Pre-release classes were found in dependencies. Remove them from the classpath, recompile with a release compiler or use '-Xskip-prerelease-check' to suppress errors
e: file:///Users/javierarroyo/Projects/Personal/Forlago/build-conventions/build/generated-sources/kotlin-dsl-accessors/kotlin/gradle/kotlin/dsl/accessors/_2fb462c0d2ba107f613d15985247d494/Accessors32ikgp1isdd8mwexzgbe6rirl.kt:65:44 Class 'io.gitlab.arturbosch.detekt.extensions.DetektExtension' is compiled by a pre-release version of Kotlin and cannot be loaded by this version of the compiler

Thanks :)

You probably need to follow steps here: https://docs.gradle.org/8.3/release-notes.html#kotlin_k2 and be sure to use Gradle 8.3 or higher.

Also have a read of https://kotlinlang.org/docs/whatsnew-eap.html#current-k2-compiler-limitations
