sw from-bottom relative orientation: add UNO API

When it comes to vertical positioning of anchored sw objects, one can
say the position should be "1cm from the top of the page". But measuring
from the bottom of something was not possible.

Add API for this to help working with documents from Word, which
supports the feature.

There is no duplicated C++ enum in sw/ for vertical relative
orientation, so no "doc model" changes are needed for this in sw/.
