[v4] MSBuild Refactor

[hunterjm]

@danielpalme - I'm getting ready to look into creating a new MSBuild project that targets both core and standard to be able to run ReportGenerator in a build pipeline. This is coming about due to comments on coverlet-coverage/coverlet#105. Before I started, I wanted to get your thoughts. Would you be up for also including a ReportGenerator.MSBuild package that basically moves the build task out of the .NET Standard console app and (hopefully) works for both core and standard?

I guess that this should be doable. Coverlet also provides a netstandard2.0
msbuild package: https://www.nuget.org/packages/coverlet.msbuild/

Creating another nuget package sounds reasonable.

Starting with this release ReportGenerator now also contains a props file.

When you install the package you can do something like this with MSBuild:

<ReportGenerator ReportFiles="OpenCover.xml" ReportTypes="Html;Badges" TargetDirectory="target\reports\coverage" HistoryDirectory="target\reports\coveragehistory" />
