since i was going to fix the include order of stdatomic, might as well sort the surrouding includes in accordance with the project's coding style. some headers can sometime require specific include order. standard library headers usually don't. but mpv might "hack into" the standard headers (e.g pthreads) so that complicates things a bit more. hopefully nothing breaks. if it does, the style guide is to blame.
