5291: Windows: Use current console background color, restore original color on exit, refactoring r=heinrich5991 a=Robyt3

- Remember initial console foreground and background color.
- Use the original background color with the message specific foreground color, so it looks better when the console background color isn't black.
- Restore the initial console foreground and background color on exit instead of leaving the color be whatever was last used.
- Add locks to ensure `Log`-calls from different threads don't overlap their output/color.
- Refactoring: Replace numbers with color constants defined in `wincon.h` (4312d20923/include/wincon.h (L51-L67)).
- Refactoring: Slightly reorder the `if`s and remove redundant checks which are ensured by the `else-if` structure.
