Adopt KUP requirements imposed by KT-75078

-Werror doesn't work with 2.0.20, so we either have to check the compiler version before using it, or update the Kotlin version (#213).

Closes #212

Can you please also add logging for all of these flags?
For example:
freeCompilerArgs.add("-Xrender-internal-diagnostic-names")
buildScriptLogger.log(LogLevel.INFO, "-Xrender-internal-diagnostic-names enabled")
freeCompilerArgs.add("-Wextra")
buildScriptLogger.log(LogLevel.INFO, "-Wextra enabled")

And can you please also add this:
implement a Gradle property for passing additional CLI options to the Kotlin compiler
(property naming is not critical but kotlin_additional_cli_options is suggested for consistency). values are space-separated (quoting values with spaces is not supported);
e.g.: -nowarn -Xwarning-level=CONTEXT_RECEIVERS_DEPRECATED:warning
The options should go after the usual ones

-Werror doesn't work with 2.0.20

Did you mean -Wextra?
Maybe we can assume that if kotlin_Werror_override=disable is specified, the version of the compiler is also overridden to one that supports -Wextra?
