Meta: Move code generator helpers to their own CMake helper file

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.
