Fix opengl issue in Window init

[Starbuck5]

Fixes #3056

I can't actually test this on Windows because it's impossible to get framebuffer acceleration on Windows in SDL2:

#if defined(__WIN32__) || defined(__WINGDK__) /* GDI BitBlt() is way faster than Direct3D dynamic textures right now. (!!! FIXME: is this still true?) */
        if (_this->CreateWindowFramebuffer && (SDL_strcmp(_this->name, "windows") == 0)) {
            attempt_texture_framebuffer = SDL_FALSE;
        }
#endif

On linux + wayland + swaywm, it does work! I'm not entirely sure I installed the branch correctly, but I see a red screen instead of black and I get opengl = False with this code:

import pygame
 
win = pygame.Window()
surf = win.get_surface()  # get the window surface
print(f"{win.opengl=}") 

while True:
   for event in pygame.event.get():
      if event.type == pygame.QUIT:
            pygame.quit()
            raise SystemExit
 
   # draw something on the surface
   surf.fill("red")
 
   win.flip()  # update the surface to the window

As mentioned on #3056 I've tested this fix on my intel MacBook Pro and the PR fixes the issue (and print(win.opengl) returns false whereas before it was returning True)
