Tables without any descendant and auto logical width should have a 0px logical width

Tables without any descendant and auto logical width should have a 0px logical width
https://bugs.webkit.org/show_bug.cgi?id=95521

Reviewed by Abhishek Arya.

Source/WebCore:

The code would wrongly add the border-spacing in the row direction to the table's logical
width even if we didn't have a column. The new behavior matches FireFox and Opera. IE
matches our old behavior for inline tables but our new behavior for normal tables which
is a bug on their side.

Tests: fast/table/empty-table-should-take-no-space.html
       fast/table/fixed-table-layout/empty-table-should-take-no-space-fixed-layout.html

* rendering/RenderTable.h:
(WebCore::RenderTable::borderSpacingInRowDirection):
Added this new helper function to return the right border-spacing. Added a FIXME as the code always
return the horizontal dimension which is wrong in vertical-writing mode.

(WebCore::RenderTable::bordersPaddingAndSpacingInRowDirection):
Changed to call borderSpacingInRowDirection. Added a comment as to why we don't add border-spacing on
border-collapse: separate tables.

Progression. The table now is 2px wide as it has a 1px right & left border.

* platform/chromium-linux/fast/invalid/residual-style-expected.txt:
Progression. The changes are due to the tables shrinking which is expected.

Progression. The tables now have a 0px logical width. In some cases, we add the border-spacing in the
block-flow direction if we have a row. This is not consistently handled by browsers and not very well
defined in CSS.
