Kotlin 1.7 incompatibility

[vkopichenko]

I tried to use this project with Kotlin 1.8.20. It was successfully adding the API dependency but the compiler plugin was not peeked up silently.

It appears that KotlinGradleSubplugin was removed in favor of KotlinCompilerPluginSupportPlugin since Kotlin 1.7:
https://kotlinlang.org/docs/compatibility-guide-17.html#remove-kotlingradlesubplugin-class

The ComponentRegistrar is deprecated too and is going to be replaced with CompilerPluginRegistrar in Kotlin 2.0.

Thanks for filing the issue! I've been trying to find the time to get the project up-to-date and working again. I did manage to get the build modernized and now I just have to find the time to finish the actual IR work.
