kotlinx-benchmark Gradle plugin should use Gradle's embedded Kotlin

[adam-enko]

Currently the kxb Gradle plugin uses Kotlin Gradle Plugin to compile the project.

kotlinx-benchmark/plugin/build.gradle

Lines 19 to 25 in 0764551

	plugins {
	id 'java-gradle-plugin'
	id 'maven-publish'
	alias(libs.plugins.gradle.pluginPublish)
	alias(libs.plugins.kotlinx.binaryCompatibilityValidator)
	alias(libs.plugins.kotlin.jvm)
	}

However, Gradle uses an embedded version of Kotlin.

Using KGP is problematic for a few reasons.

• KGP adds dependencies that might clash with other Gradle plugins (e.g. adds kotlin-stdlib as a dependency, but this will be provided by Gradle.)
• kxb Gradle misses compiler arguments (e.g. -java-parameters) that maximise compatibility with other Gradle plugins.

In order to maximise compatibility with Gradle, kxb Gradle should use the kotlin-dsl plugin instead of KGP. (This might lead to lots of code changes though, because it applies sam-with-receiver - a quicker fix would be to use embedded-kotlin instead of KGP.)
