When transparency is present, it's not enough to just write 32bpp samples.
One need to use the full BITMAPV3INFOHEADER syntax and specify the
masks for BGRA.
see https://en.wikipedia.org/wiki/BMP_file_format#Pixel_storage
Also remove the height-flip trick and write samples bottom-to-top instead.

Bug: b:185520494
Visual Studio added ARM64 support, but requires arm64_neon.h to be
included rather than arm_neon.h. Visual Studio 2019 addressed this so
we'll start with that version and leave a local adapter include for a
follow up.
