        Add WKStringGetCharactersPtr() and WKStringGetLength() to WebKit2 C API
        https://bugs.webkit.org/show_bug.cgi?id=57989
        
        Note that WKChar, which is returned by WKStringGetCharactersPtr(), is defined the same way we define JSChar in JSStringRef.h.

        * Shared/API/c/WKString.cpp:
        (WKStringGetLength): Added.
        (WKStringGetCharactersPtr): Added.
        * Shared/API/c/WKString.h: Define WKChar and added WKStringGetLength() and WKStringGetCharactersPtr().
        * Shared/WebString.h:
        (WebKit::WebString::length): Added.
        (WebKit::WebString::characters): Added.
