tdf#118361 sw ooxmlimport: set footnote separator alignment

If RTL is defined in the default (Normal) paragraph style,
then the footnote separator should be right-aligned.
In MSWORD, the alignment is not a property that is stored
with the footnote separator definition, and it is not a
page property like it is in LO.
The reverse needs to happen for LTR default paragraph style.

Based on my MSWORD observations, the only place where you can
indirectly set RightToLeft is in the "Normal" paragraph style.
That option is disabled in all of the other styles.

In LibreOffice, this is typically handled by the locale properties.
The default PAGE style's Footnotes - Position is RIGHT for
RTL locales, but LEFT for LTR locales.

It is kinda interesting that no one from a RTL locale complained
about wrongly-right-aligned footnote separator
from imported LTR .docx's.

None of this belongs in export code, since MSO doesn't support
specifying the location - it is just a consequence of the
RTL/LTR settings.
