Rename InlineIterator::m_obj and make it private
https://bugs.webkit.org/show_bug.cgi?id=124837

Reviewed by Antti Koivisto.

InlineIterator has been exported m_obj as public though there is a getter function.
Besides *object* name isn't ambigious. So, changed it with m_renderer and renderer().
Additionally, setRenderer() is added as well.

No new tests, no behavior changes.
