Support install EXE nuget packages

sdflysha

Please enable support for "Command Line" like nuget packages, these package contains EXE.
For example: after installing package 7-Zip.CommandLine, so I can *make sure* there is a 7zip.exe on my machine, should be at %LocalAppData%\LINQPad\NuGet.FW46. So I can then call this command line tool with Util.Cmd

Same other command line nuget package includes:

https://www.nuget.org/packages/FFmpeg.Win64.Static/
https://www.nuget.org/packages/Selenium.Chrome.WebDriver/

This is timely, because I'm currently re-writing the NuGet integration in LINQPad 6. The new downloader generates a warning rather than an error when there are no usable assemblies, so you can successfully download packages that contain just tools.

I will also add a method to the NuGetReference class called "GetPackageFolders" to make it easier to find the target folder, so you can do this in the case of 7zip:

string packageFolder = Util.CurrentQuery.NuGetReferences
    .First (r => r.PackageID.Equals ("7-Zip.CommandLine", StringComparison.OrdinalIgnoreCase))
    .GetPackageFolders()
    .Single();
    
string exePath = Path.Combine (packageFolder, "tools", "7za.exe");

exePath will then be set to this:

%userprofile%\.nuget\packages\7-zip.commandline\18.1.0\tools\7za.exe
