This fixes CORE-15708 "PdfSam 3.3.5 setup can not decode bmp" https://jira.reactos.org/browse/CORE-15708 Wine does not have this issue, but it did not have it back when last sync to WineStaging-4.18 was done. This commit is as near as possible to actual wine-7.0-rc3 version. This wine code uses reverse_bgr8 instead of own convert_rgba_to_bgra, but it leads to wrong colors.
