video: Update the popup window creation documentation and disallowed flags 

Update the popup window creation documentation with additional info, remove the SDL_WINDOW_MOUSE_GRABBED flag check since it isn't a valid window creation flag and will be removed automatically elsewhere, and check for and remove the explicit skip taskbar and borderless flags since they are implicit for popup windows.
