Update to sdk-style csproj and netstandard2.0. (#78)

Update `Xamarin.Android.Tools.AndroidSdk` to use sdk-style projects
and target frameworks `netstandard2.0` and `net461`.

Update `Xamarin.Android.Tools.AndroidSdk-Tests` to use sdk-style projects.

Move `Xamarin.Android.Tools.AndroidSdk-Tests` into a `tests` directory
to avoid sdk-style globbing.

Use MSBuild properties for NuGet packages instead of .nuspec.

Update `MicroBuild.Core` to `Microsoft.VisualStudioEng.MicroBuild.Core`.

  * Not sure what this does but [the docs][0] said the old one was
    deprecated and pointed to the new one which supports
    `netstandard2.0`.
