CORS: Take a std::initializer_list in cors_error_string.cc's Append()

Follow-up to fc0443b1 ("Update CORS error messages"), which broke the GCC
build because GCC does not implicitly covert all array items to StringViews
when Append() is invoked:

    ../../third_party/blink/renderer/platform/loader/cors/cors_error_string.cc: In function ‘WTF::String blink::CORS::GetErrorString(const network::CORSErrorStatus&, const blink::KURL&, const blink::KURL&, const blink::SecurityOrigin&, blink::Resource::Type, const WTF::AtomicString&)’:
    ../../third_party/blink/renderer/platform/loader/cors/cors_error_string.cc:72:55: error: no matching function for call to ‘Append(WTF::StringBuilder&, <brace-enclosed initializer list>)’
                        last_request_url.GetString(), "' "});
                                                           ^

      void Append(StringBuilder& builder, const StringView (&views)[N]) {
          ^~~~~~

                                                           ^

Make the local Append() function take a std::initializer_list<StringView> to
make sure all items are converted to that type on invocation.
