[WebView Support Library] Implement onReceivedError

This is the second CL in a series to implement WebViewClientCompat.

This implements WebViewClientCompat#onReceivedError() and adds the
abstract class WebResourceErrorCompat.

We define 3 signatures for onReceivedError():

 1. Inheriting the WebViewClient method with WebResourceError (called by
    legacy WebView APKs on 23+)
 2. Implementing the boundary interface method with an InvocationHandler
    (called by up-to-date WebView APKs)
 3. A new signature which uses WebResourceErrorCompat (which apps may
    override)

Signatures 1 and 2 convert their parameter into a WebResourceErrorCompat
and invoke signature 3. Signature 3 also implements default behavior
resembling the corresponding WebViewClient method.

Test: Manual - build a test app with WebViewClientCompat
