Adds a constructFiles option that allows for easier creation of generated files in which placeholders such as ${placeholder "out"} work

From inside the module, you can

config.constructFiles.<name> = {
  content = "some file content";
  relPath = "some/path";
};
# you can get the resulting placeholder path with config.constructFiles.<name>.path

It also provides a read-only config value that allows the placeholder file location to be easily accessible outside of the derivation.

In addition, on the resulting package, all the values in config are accessible via passthru.configuration

This means you can yourWrappedPackage.configuration.constructFiles.<name>.outPath to get the final path to it from outside of the wrapper module, without having to worry about making sure placeholders resolve correctly yourself.

Note, that will not work inside the module. Inside the module, you will want to use config.constructFiles.<name>.path.

Also note that attribute sets with .outPath in them can be directly interpolated.

Outside the module, you can also get the path with "${yourWrappedPackage.configuration.constructFiles.<name>}"
