kotlinx-serialization-hocon can not be used without kotlinx-serialization-core

[osipxd]

Describe the bug It is impossible to use kotlinx-serialization-hocon without kotlinx-serialization-core added explicitly because core module is added with implementation configuration in hocon module: https://github.com/Kotlin/kotlinx.serialization/blob/d5bc32dc11d2a8a08c36663b93839d4fe91f4507/formats/hocon/build.gradle#L22

To Reproduce

1. Add kotlinx-serialization-hocon to dependencies.
2. Try to use annotation @Serializable.
3. You will get an errors like:

Unresolved reference: Serializable

Expected behavior core module should be added to dependencies transitively

Environment

• Kotlin version: 1.7.10
• Library version: 1.3.3 and 1.4.0
