The compositor execute functions have a `rendering` argument to specify if the compositor is executing as part of the render pipeline. But the render context argument is null if we are not rendering, so the `rendering` arguement is redundant and can be removed. Additionally, we no longer use use_file_output as a hack to detect rendering. Pull Request: https://projects.blender.org/blender/blender/pulls/120659
