        Introduce WebFileChooserParams to convey parameters for

        WebViewClient::runFileChooser(), and add new parameters to it.

        https://bugs.webkit.org/show_bug.cgi?id=32473

        The new parameters are

         - selected file names

         - "accept" attribute value

        * WebKit.gyp: Add WebFileChooserParams.h

        * public/WebFileChooserParams.h: Added.

        * public/WebViewClient.h:

        (WebKit::WebViewClient::runFileChooser):

          Add runFileChooser() with WebFileChooserParams, and mark the old one deprecated.

        * src/ChromeClientImpl.cpp:

        (WebKit::ChromeClientImpl::runOpenPanel):

          Call the new runFileChooser() first, then call the old

          runFileChooser() if the new one failed.

                'public/WebFileChooserParams.h',
