/*
 * This method is responsible for loading a project.godot file and/or data file
 * using the following merit order:
 *  - If using NetworkClient, try to lookup project file or fail.
 *  - If --main-pack was passed by the user (`p_main_pack`), load it or fail.
 *  - Search for project PCKs automatically. For each step we try loading a potential
 *    PCK, and if it doesn't work, we proceed to the next step. If any step succeeds,
 *    we try loading the project settings, and abort if it fails. Steps:
 *    o Bundled PCK in the executable.
 *    o [macOS only] PCK with same basename as the binary in the .app resource dir.
 *    o PCK with same basename as the binary in the binary's directory. We handle both
 *      changing the extension to '.pck' (e.g. 'win_game.exe' -> 'win_game.pck') and
 *      appending '.pck' to the binary name (e.g. 'linux_game' -> 'linux_game.pck').
 *    o PCK with the same basename as the binary in the current working directory.
 *      Same as above for the two possible PCK file names.
 *  - On Android, look for 'assets.sparsepck' and try loading it, if it doesn't work,
 *    proceed to the next step.
 *  - On relevant platforms (Android/iOS), lookup project file in OS resource path.
 *    If found, load it or fail.
 *  - Lookup project file in passed `p_path` (--path passed by the user), i.e. we
 *    are running from source code.
 *    If not found and `p_upwards` is true (--upwards passed by the user), look for
 *    project files in parent folders up to the system root (used to run a game
 *    from command line while in a subfolder).
 *    If a project file is found, load it or fail.
 *    If nothing was found, error out.
