Simple compilation of a kotlin library using a non-persistent worker. The target is a JavaInfo provider.
The target is tagged `"no-ide"` as intellij can't compile it. A seperate private target is created which is suffixed
with `_for_ide`. If the dep is under the package `//kotlin/builder/src/io/bazel/kotlin/builder/...` then it will be
added to the `_for_ide` target by adding a `_for_ide` prefix.
deps: the dependenices, the are setup as runtime_deps of the library.
neverlink_deps: deps that won't be linked. These deps are added to the `"for_ide"` target.
