Dependency Updates

[ElektroKill]

Currently, dnSpy relies on quite old versions of certain libraries. For obvious reasons, the dependencies should be updated.

List of outdated dependencies:

• [ ] ILSpy: tracked by https://github.com/dnSpyEx/dnSpy/issues/5
• [x] Roslyn: Currently dnSpy uses Roslyn 2.10 which should be updated to the latest, as of now 3.11 version. the API has changed from version 2 to 3 so the ExpressionCompiler project and other dnSpy projects will need to be updated for the new API.
• [x] Mono.Debugger.Soft - dnSpy uses a version of this library from 11th November 2017. Since this library is used heavily by the dnSpy Mono debugger updating it will probably improve that component.
• [x] VisualStudio Text and Intellisense components - these NuGet packages are also a bit out of date and the newer versions have some API changes which makes an update trickier.
• [x] ClrMD (Microsoft.Diagnostics.Runtime) - Updating is not possible as it would break compatibility with .NET Framework 2.0, 3.5, and 4.0.

It seems that updating the VisualStudio Text and Intellisense components has been made impossible due to the fact that newer versions of the packages only target .NET Framework and not .NET Standard. https://www.nuget.org/packages/Microsoft.VisualStudio.Text.UI.Wpf/#dependencies-tab https://www.nuget.org/packages/Microsoft.VisualStudio.Language.Intellisense/#dependencies-tab
