With regular builds, the generated IPC headers exist inside the Build
directory. The path Userland/Services under the build directory is
added to the include path.
For in-system builds the IPC headers are installed at /usr/include/.
To support this, we add /usr/include/Userland/Services to the build path
when building from Hack Studio.

This is needed so all headers and files exist on disk, so that
the sonar cloud analyzer can find them when executing the compilation
commands contained in compile_commands.json, without actually building.

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.
