This PR attempts to improve the dotnet portable executable identification.

Fixes: #2029

In order to try to determine reasonable behavior, I created a spreadsheet of all the PE Version Resources from:

The general pattern in this limited data set seems to be: Microsoft PE files used the FileDescription while non-Microsoft vendors provided reasonable values in the ProductName. Additionally, this PR attempts to improve version detection based on some examples found in the wild.

Sorry for the delay @cichy3000 -- I didn't want to get a change like this merged without some due diligence looking at examples in the wild to make sure we're not regressing. As noted in the description there's a spreadsheet with a lot of examples that was used to determine the behavior implemented in this PR
