This adds a new main command-line entry point for hdrgen, in the new main.py. This new interface is used for generating a header. The old ways of invoking yaml_to_classes.py for other purposes are left there for now, but `--e` is renamed to `--entry-point` for consistency with the new CLI. The YAML schema is expanded with the `header_template` key where the corresponding `.h.def` file's path is given relative to where the YAML file is found. The build integration no longer gives the `.h.def` path on the command line. Instead, the script now emits a depfile that's used by the cmake rules to track that. The output file is always explicit in the script command line rather than sometimes being derived from a directory path.
