Implement System.ComponentModel.VersionConverter (dotnet/corefx#28516)

* Implement System.ComponentModel.VersionConverter

VersionConverter is a new System.ComponentModel.TypeConverter subclass that handle conversions between string and System.Version.

* Fix tests build for VersionTypeConverter

* Use Version.Parse() instead of new Version() to save an allocation

* Add test data to ensure that the version string is trimmed

* Call base class implementation instead of explicitly throwing

* Always throw a FormatException when a version string is invalid
