Set m_pos as private in InlineIterator, and use getter and setter functions.
https://bugs.webkit.org/show_bug.cgi?id=125614

Reviewed by Alexey Proskuryakov.

InlineIterator has been exported m_pos as public directly though it is member variable.
This patch set it as private, and add getter/setter functions for it.

No new tests, no behavior changes.
