tdf#82177 docx export: eliminate invalid tbl insideV/H borders

Inherited from OOo, these insideV/H borders incorrectly assume
that every inside border will match the bottom/right border
of cell A1. For the most part this error is harmless since
every cell specifies every border anyway (that doesn't match
a table-style default). The only time it is visible is when
insideV/H specifies a border, but none is set on the cell.

The problem is that these pseudo-defaults are not passed
to the cellborders function as defaults, so cells have no idea
whether they need to override these values or not.

Since the implementation is completely flawed and unnecessary,
simply eliminate it.

(TODO: In fact, the entire tblBorders output is flawed,
as demonstrated by the outside borders in the unit test.)

One unit test is removed since insideV/H is no longer
being written (this was just a "lets specify what we
see being written out" test, not one concerned specifically
with insideV/H. Not enforcing the absence of insideV/H because
theoretically someone could legitimately add zero-width
borders to the table borders and still be valid.

The ordering of the borders test was moved from a
table borders test (no longer created) to a styles
border (which is still valid - a grabbag dump.)
