cmGeneratorExpressionNode: implement `COMPILE_ONLY` genex
This generator expression is the inverse of `LINK_ONLY` and only coveys
usage requirements for the purposes of compilation. Its intended use is
to avoid needing to export targets that do not have link usage
requirements (e.g., header-only libraries) when used by another target.
See: #15415
