Resolves: #i123228# ParagraphData symbols shouldn't be required...

for outlobj.hxx users

Avoid the ParagraphDataVector default constructor in the editeng/outlobj.hxx
header. ParagraphData symbols are not DLLPUBLIC so they are not available
outside of editeng. When inlining is disabled (e.g. for debugging) this may
break the build as observed when building svx in debug mode on Solaris.
