Decouple Kotlin compiler from Kotlin rules

Move Kotlin specific targets (like `kt_jvm_import`) from `BUILD.com_github_jetbrains_kotlin` to `//kotlin/compiler`.

This will make it possible to release `kotlin-compiler` module on `bazel-central-registry` without depending on `rules_kotlin`. The release will contain the new form `BUILD.com_github_jetbrains_kotlin` which doesn't depend on `rules_kotlin`.

RELNOTES[INC]: This breaks users that depend on `@com_github_jetbrains_kotlin//:*` targets. The same targets can be found under  `@io_bazel_rules_kotlin//kotlin/compiler:*`.

It's not possible to add an `alias` to `@com_github_jetbrains_kotlin` repository, becuase it would already create a dependency on `rules_kotlin` repository in the bzlmod world.

Technically it's possible to release 2 bzlmod modules that have a circular dependency. But this might create some unexpected problems. It addition it would be harder to convince `com_github_jetbrains_kotlin` owners to depend on `rules_kotlin`.

Works toward: bazelbuild#660
