1.9.0

• Update to Kotlin 2.0.0 (aka K2). This plugin now assumes 2.0, but can be used with Kotlin 1.9.x as well.
• Fully implement validation checks in FIR, allowing the plugin to report errors earlier and also (eventually) have errors appear automatically in the IDE.
  • The IR plugin no longer validates by default.
  • At the time of writing, I'm not able to get errors to appear in the IDE even if non-bundled plugins are force-enabled. Follow KTIJ-29248 for more info.
• The enabled compiler option is no longer required and just defaults to true.
• Omit the stdlib from transitive dependencies on the compiler plugin and Gradle plugin artifacts. Both kotlinc and Gradle impose their own versions on the classpath.
