compile_gml, compile_ipc, and generate_state_machine all use host tools to generate sources for the target build. As part of trying to organize host tools into a common area, let's move these helper rules to a common file that we can add other host tools to later. And, keep the host tool helpers separate from the CMake target helpers for apps and libraries.
