Blitting from a higher bit depth source to a lower bit depth
destination was not working properly because Vulkan expects
clamping, while the blitter was truncating the values.

From section 19.5. Image Copies with Scaling:
"Signed and unsigned integers are converted by first
 clamping to the representable range of the destination
 format, then casting the value."

This fixes all remaining failures in:
dEQP-VK.api.copy_and_blit.core.blit_image.all_formats.color.*
