Adjustments in InlineTextBox.

* updateGraphicsContext and correctedTextColor are not used anywhere
  else, so they are made static functions
* correctedTextColor sheds unnecessary generality (backgroundColor is
  always Color::white)
* InlineTextBox::textRenderer is inlined at its declaration, which
  is more concise and easier to find

[ServiceWorker] Catch up to a change in the Fetch spec

This change follows the change in Fech spec
https://github.com/whatwg/fetch/commit/540a828e4bff394c1b44abef9a94424cac3fbea1
https://github.com/whatwg/fetch/issues/9

In current code:
 var baseRequest = new Request('test.html', {headers: {'X-Test': 'test'}});
 var request = new Request(baseRequest, {mode: 'no-cors'});
 console.log(request.headers.get('X-Test'))  // -> 'test

Expected:
 'X-Test' header should be omitted in the constructor of |request| because the mode is 'no-cors'.
