related tdf#99602 writerfilter TODO: subscript - use ParaStyle fontsize

The existing code handled two situations:
1.) if both position(escapement) and fontsize set via direct properties
2.) if fontsize came from the document default properties.

That misses both paragraph style fontsize (very common)
and character style fontsize.  This patch adds checking for
the paragraph style's fontsize.
