chamelium: Pass and use stride for xr24 pattern paint
Using the width from the selected mode is not sufficient to correctly
paint a pattern on the framebuffer memory: the stride also has to be
taken in account for proper line start alignment.
Pass the stride and use it in chamelium_paint_xr24_pattern.
