Migrate "[assembly: Parallelize(Scope = ExecutionScope.MethodLevel)]" to SDK project file

[SetTrend]

Current Situation

Currently, when a new MS Test SDK project is being created, an additional C# file is being generated ("MSTestSettings.cs") that's bloating the file list and may accidentally be deleted when using wildcards to delete a number of tests.

Desired Situation

Please provide an SDK project property to have this setting available there and remove the additional C# file from the project template.

Not sure why I didn't think of it before but that's a really good suggestion!
