Remove unnecessary makePropertyValue specialization for Any

...that had been introduced with 9e87a00e "oox:
replace PUT_PROP macro with comphelper::makePropertyValue() calls", but for
reasons unclear to me.  toAny is specifically there to either wrap its argument
in an Any or, if the argument already is an Any, pass it on unwrapped.  There
is no deleted toAny overloads or explicit specializations.
