PowerToys Svg thumbnail failed rendering

Summary of the Pull Request

Default value of fill-rule in style is "nonzero". There is a possibility that rendering bugs may occur due to this reason. Therefore, to eliminate these errors, it is checked whether there is a fill-rule in style and if so, it is re-applied.

Detailed Description of the Pull Request / Additional comments

I created some SVG files for testing. The first one is the "fill-rule" attribute is under style. In others it's under "polygon" and "path". When I tested it with version 0.84.1, only the one under style was broken. Therefore, I was able to solve the problem by parsing the svg style of the file and re-applying the "fill-rule" and other attributes there. The reason why I re-applied all the attributes in the style was that if there was such an error in the "fill-rule", I suspected that there might be other attributes as well. When I changed the "stroke color", "clip-rule", "stroke-width", "opacity" attributes, I did not encounter this error. However, I preserved the code this way as similar errors may occur in other attributes in the future.

0.84.1 test files with release
