feat: Add ExportFiles command to WKit Scripting

[dragonzkiller]

Implemented:

• Export files from wkit scripts (requires file to already be added to project)

// export either a single item
wkit.ExportFiles("base\\gameplay\\gui\\world\\arcade_games\\roach_race\\art\\roach_race_sprites_1080p.xbm");

// or an array of items
wkit.ExportFiles(["base\\gameplay\\gui\\world\\arcade_games\\roach_race\\art\\roach_race_sprites_1080p.xbm",
    "base\\gameplay\\gui\\world\\arcade_games\\roach_race\\art\\roach_race_sides.xbm"]);

// function can warn of files that do not exist in the project
wkit.ExportFiles(["base\\gameplay\\gui\\world\\arcade_games\\roach_race\\art\\roach_race_sprites_1080p.xbm",
    "base\\gameplay\\code\\CDPR_bugless_code\\literally_anything.cpp"]);

// function can error on invalid type conversions (e.g. random integer)
wkit.ExportFiles(0);
wkit.ExportFiles(["base\\gameplay\\gui\\world\\arcade_games\\roach_race\\art\\roach_race_sprites_1080p.xbm",
    0]);

Please feel free to murder my code and clean it up, or suggest new function names, etc. There's also more nasty type things because of the V8 interpreter.

should be fine
