[Windows] A file without .scale-xyz qualifier is generated for each SVG

[MartinZikmund]

Current behavior

For each svg file on Windows, all scales get generated + plain .png without the scale-xyz qualifier - this file is redundant, Windows will use the closest scale as the fallback automatically. Same thing should be true for Skia desktop targets

Expected behavior

Remove the unnecessary file without scale qualifier.
