[Bug] Kotlin2Cpg fails when kotlin 2.x compiler is present

[tajobe]

The kotlin2cpg frontend uses at least one function from the compiler that is only available on 1.x, meaning it fails for kotlin 2.x

I am invoking the frontend from a kotlin 2.x project which uses kotlin scripting and thus embeds its own kotlin compiler, meaning at runtime it seems to resolve the 2.x compiler rather than the embedded one in the kotlin2cpg frontend.

See:

joern/joern-cli/frontends/kotlin2cpg/src/main/scala/io/joern/kotlin2cpg/types/TypeRenderer.scala

Line 88 in 398af04

val isWrapperOfPrimitiveType = JvmPrimitiveType.isWrapperClassName(fqName)

This uses JvmPrimitiveType.isWrapperClassName, which seems to have been renamed in 2.x to JvmPrimitiveType.isWrapperClassInternalName, causing a failure for 2.x kotlin projects.

Partial stacktrace:

java.lang.NoSuchMethodError: 'boolean org.jetbrains.kotlin.resolve.jvm.JvmPrimitiveType.isWrapperClassName(org.jetbrains.kotlin.name.FqName)'
	at io.joern.kotlin2cpg.types.TypeRenderer.maybeUnwrappedRender(TypeRenderer.scala:88)
	at io.joern.kotlin2cpg.types.TypeRenderer.renderForDescriptor$$anonfun$1(TypeRenderer.scala:106)

To Reproduce
Steps to reproduce the behavior:

1. Attempt to invoke the kotlin2cpg frontend with kotlin 2.x compiler on the classpath

Expected behavior
CPG is created successfully
