Encoding the image found in the user bug report below would result in
a progress rising up to 173% because of the extra 20% caused by each
of the 4 extra lossy passes. It happened at methods 3 to 6.

(cherry picked from commit db25f1b4ed2ef519b6a3fd1d7ebfbcdfe2cc9712)
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.

WebPPictureImportRGB() can fail on memory allocation. In this case,
jpeg_destroy_decompress() was already called, so do not go to Error.
Free metadata as an error is returned.

images are decoded in RGBA/BGRA, but represented as uint32_t during the
blend process; this fixes the channel extraction

Similarly to "-set loop <>", this is useful to set
the parameter at global level and not just while assembling

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.
