Remove embedded-kotlin-repo and pin Kotlin dependencies with constraints

@@ -711,8 +711,6 @@ The plugin achieves this by doing the following:
 
  * Applies the link:https://kotlinlang.org/docs/reference/using-gradle.html#targeting-the-jvm[Kotlin Plugin], which adds support for compiling Kotlin source files.
  * Adds the `kotlin-stdlib-jdk8`, `kotlin-reflect` and `gradleKotlinDsl()` dependencies to the `compileOnly` and `testImplementation` configurations, which allows you to make use of those Kotlin libraries and the Gradle API in your Kotlin code.

-All three libraries and their dependencies are bundled with Gradle, so these dependencies will not result in any downloads.
  * Configures the Kotlin compiler with the same settings that are used for Kotlin DSL scripts, ensuring consistency between your build logic and those scripts.
  * Enables support for <<kotdsl:precompiled_plugins,precompiled script plugins>>.

 Tasks extending `AbstractCompile` can implement their own `@TaskAction` method with the name of their choosing.
 They are also free to add a `@TaskAction` method with an `InputChanges` parameter without having to implement a parameter-less one as well.

 ==== Kotlin DSL IDE support now requires Kotlin IntelliJ Plugin >= 1.3.50
 
 With Kotlin IntelliJ plugin versions prior to 1.3.50, Kotlin DSL scripts will be wrongly highlighted when the _Gradle JVM_ is set to a version different from the one in _Project SDK_.
