xmloff: ODF export: rework version checks in SvXMLExportPropertyMapper

There's some issues with the version checks here:

* The requirement is to retain support for ODF 1.2 extended,
  but some attributes are in ODF 1.3, while others require ODF 1.3
  extended, so a single version number can't be used to compare

* A recurring problem is that new extension attributes are erroneously
  exported to standard namespaces;
there is the pre-existing buggy case of style:hyperlink to
consider...

* Currently it's possible to distinguish multiple extended version but
  the only minimum version that's actually used is the minimum one
  ODFSVER_012_EXT_COMPAT

Rework this to use a different check, by:

* distinguishing extension attributes from standard attributes via
  their namespace, to avoid such bugs by construction

* interpreting the version number always as a standard ODF version
number:

    if the attribute is in extension namespace:
        if the minimum standard version is met, ignore
    else:
        if the minimum standard version is met, export

* adapting all XMLPropertyMapEntry to use ODFSVER_FUTURE_EXTENDED for
extension attributes (TODO: check which of these should be
ODFSVER_013)

This should have an effect on the drawext:fontwork* attributes, which
need ODFSVER_FUTURE_EXTENDED to be exported now.
