Remove JvmBytecodeBinaryVersion from the compiler code
Move it to build-common where it's still used in incremental compilation caches, and simplify a bit. In the future, it'll make sense to remove it completely and to avoid writing it to caches. In this commit, I don't do that to prevent the IC cache version to be updated, causing rebuilds for all JPS projects. #KT-41758
