Xamarin Support (dotnet#1360)

* Multi-target `BenchmarkDotNet.Samples` to include `netstandard2.0`
* Don't probe for `mono` binary for `InProcess`
* Detect Xamarin.Android / Xamarin.iOS
* Fix for `Directory.CurrentDirectory()` as `ArtifactPath`
* Default to `InProcess` for Xamarin platforms
* Added documentation, sample, and a new `BenchmarkDotNet.Xamarin.sln`

+## Sample: IntroXamarin
+
+To use BenchmarkDotNet with Xamarin, you will need to build a small UI for running Benchmarks and displaying the results so you can actually read them.
+Using [Xamarin.Forms](https://dotnet.microsoft.com/apps/xamarin/xamarin-forms) is a simple way to be able to run your benchmarks on iOS or Android.
+
+Other notes:
+
+* Use `Release` builds when running actual benchmarks.
+* Disable the linker via the `Don't Link` or `None`.
