Fix zoom handling and update screen calculations

Browse source 
- Corrected loop bounds in 'GrZoomInScreen' to use 'GR_HEIGHT' and 'GR_WIDTH' constants instead of dynamic values from 'gr.dc2'.
- Updated 'src' offset calculations to use 'GR_WIDTH' instead of 'gr.dc2->width_internal'.
- Simplified 'GrUpdateScreen32' to use fixed 'GR_HEIGHT' and 'GR_WIDTH' values for screen updates, removing unnecessary calculations and size adjustments based on 'gr.dc2' and 'gr.zoomed_dc'.
