Create new targets for K1 and K2-specific jars for the IDE. (These
contain the diagnostics classes generated by the plugins, used to target
quickfixes.)
The existing `parcelize-compiler-plugin-for-ide` target remains
untouched with a K1 JAR dependency, because IJ currently depends on
this. Once IJ is cleaned up, we can remove the K1 reference from that
target, leaving only code shared between frontends.
