We previously tried to implement the [table specification algorithm] for
distributing the inline size of cells with `rowspan` > 1. This algorithm
isn't great though, so this change starts switching Servo to using an
algorithm like the one used in LayoutNG from blink. This leads to
improvements in test results.
Limitations:
- Currently, non-fixed layout mode is handled, but a followup change will
very likely addressed fixed mode tables.
- Column merging is not handled at all.
Fixes#6578.

* Fix size of tables in flow layout
The contents of a table can make it bigger than what we would expect
from its 'width', 'min-width', 'height' and ' min-height' properties.
Also, 'width: auto' doesn't stretch it to fill the containing block.
We had to refactor the resolution of margins to happen after layout,
otherwise 'auto' margins wouldn't align correctly.

* Feedback
* Consistently use `containing_block_for_table` in table layout
* Update test result

This implements a very naive row height allocation approach. It has just
enough to implement `vertical-align` in table cells. Rowspanned cells
get enough space for their content, with the extra space necessary being
allocated to the last row. There's still a lot missing here, including
proper distribution of row height to rowspanned cells.

This adds support for table `border-spacing` property. Note that we do
not yet support the collapsed border model.
