Kotlin JPS plugin: drop intellij-core dependency

Drop dependency because
https://youtrack.jetbrains.com/issue/IDEA-292483/UnsupportedClassVersionError-when-trying-to-run-JUnit5-unit-test#focus=Comments-27-6034750.0-0

IDEA plans to drop `PathUtil` from JPS classpath, we should prepare to
that

`KotlinFacetSettingsProvider` isn't used in jps so it was moved into
intellij repo. It was moved to
`community/plugins/kotlin/idea/src/org/jetbrains/kotlin/config/KotlinFacetSettingsProvider.kt`
path (so you can find it git history)
