tdf#162211 tdf#160077 layoutInCell: use row margin for MSOLayout

I think the bottom margin functions might be buggy,
so I'm glad I don't need to use them
(since MSO only does vertical layout against the top).

This is only needed for "from top",
because the only other choice, "top",
is based on the print area, while this function
uses GetFrameArea. GetFramePrintArea is invalid,
so that can't be used directly.

make CppunitTest_sw_ooxmlexport21 \
CPPUNIT_TEST_NAME=testTdf160077_layoutInCell
make CppunitTest_sw_ooxmlexport21 \
CPPUNIT_TEST_NAME=testTdf160077_layoutInCellB

Before this patch could pass sw.check,
I had to fix the following unit test in a previous patch
make CppunitTest_sw_layoutwriter2 CPPUNIT_TEST_NAME=testTdf116256
