Introduce kotlin-jps-plugin and deprecate kotlin-jps-plugin-classpath

`kotlin-jps-plugin-classpath` isn't dropped because, in some places, IDE
depends on the old artifact so I want to keep it for a while until I
cleanup IDE completely.

I tried to put as much libraries into `kotlinJpsPluginMavenDependencies`
as possible in the previous commit. Right now,
`kotlin-jps-plugin-classpath` is 33Mb, `kotlin-jps-plugin` is 20Mb (all
are not compresed)
