[API CHANGE] PPTX filter: fix lost hide-while-show prop for slide narrations

The OOXML markup is <p:cMediaNode ... showWhenStopped="0">, but the UI
uses "Hide During Show", which is easier to understand, so use the
second naming in the code.

With this, the PPTX no longer makes the speaker bitmaps on slides
visible while projecting.

API change, because the animation node is only available via UNO, though
it's likely that no actual external code would ever interact with it
directly. (And also add a stub Narration attribute, so that can be
implemented in a follow-up commit without an API change.)
