Add WebView.evaluateJavaScript(String, ValueCallback) API.

This API is intended to replace the "WebView.loadUrl("javascript:...")
pattern that is the current mechanism for executing JavaScript in the
context of the current page displayed in the WebView.

The new API is more convenient - it doesn't trigger the normal URL
loading path - and so does not have side effects such as hiding
the keyboard - and allows the caller to specify a callback that will
be invoked once the script execution is complete.
