Remove remaining \file tags from comments

[Sackzement]

Removed the \file tag from all files except from SDL.h.

Tried to remove it from SDL.h as well like this:

diff --git a/include/SDL3/SDL.h b/include/SDL3/SDL.h
index e9f1d6bee..1c34c5c42 100644
--- a/include/SDL3/SDL.h

+/* Main include header for the SDL library, version 3.1.3 */
 
 #ifndef SDL_h_
 #define SDL_h_

... but then the github workflows for all Ubuntu tests failed with following error:
