Sylvain Becker 7b8bac5958 Add fast paths in BlitNtoNKey
All following conversions are faster (with colorkey, but no blending).
(ratio isn't very accurate)

ABGR8888 -> BGR888 :  faster x9   (2699035 -> 297425)

ARGB8888 -> RGB888 :  faster x8   (2659266 -> 296137)

BGR24 -> BGR24 :  faster x5   (2232482 -> 445897)
BGR24 -> RGB24 :  faster x4   (2150023 -> 448576)
