Add a warning for a user who sets `compose.kotlinCompilerPlugin` to `androidx.compose.compiler.compiler` (#3313)

* Add a warning for a user who sets `compose.kotlinCompilerPlugin` to `android.compose.compiler.compiler`

The warning will show up only when a multiplatform project contains at least one of the non-jvm targets: k/js, k/native or k/wasm

* fix typo

* PR review

* Refactor to BuildService

* fix typo
