ui/sdl2: set swap interval explicitly when OpenGL is enabled
Before 176e3783f2ab (ui/sdl2: OpenGL window context)
SDL_CreateRenderer was called unconditionally setting
the swap interval to 0. Since SDL_CreateRenderer is now no
longer called when OpenGL is enabled, the swap interval is
no longer set explicitly and vsync handling depends on
the environment settings which may lead to a performance
regression with virgl as reported in
https://gitlab.com/qemu-project/qemu/-/issues/2565
Restore the old vsync handling by explicitly calling
SDL_GL_SetSwapInterval if OpenGL is enabled.
Fixes: 176e3783f2ab (ui/sdl2: OpenGL window context)
Closes: https://gitlab.com/qemu-project/qemu/-/issues/2565
