hw/display/blizzard: Expand out macros 

Now that we can assume that only depth 32 is possible, there's no need
for the COPY_PIXEL1 and PIXEL_TYPE macros, and the SKIP_PIXEL, COPY_PIXEL
and SWAP_WORDS macros aren't used at all. Expand out COPY_PIXEL1 and
PIXEL_TYPE where they are used, delete the unused macro definitions, and
expand out the uses of glue(name_prefix, DEPTH).
