[dotnet] Restore removed RemoteWebElement class

The RemoteWebElement class has been replaced by the WebElement base
class. This version of RemoteWebElement is simply a subclass that does
nothing but provide the existence of the class. All functionality is
provided by the base WebElement class. Downstream projects that have
element classes that subclass RemoteWebElement should update their code
to subclass WebElement instead. Users should not be using
RemoteWebElement or WebElement; they should be using the IWebElement
interface instead.
