For a table wrapper in collapsed-borders mode we were just halving the
border widths from the computed style. However, it needs to actually
receive half of the resulting collapsed border, which can be bigger.

We were actually using the opposite order.

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.

We were previously splitting collapsed borders into two halves, and then
paint each one as part of the corresponding cell. This looked wrong when
the border style wasn't solid, or when a cell spanned multiple tracks
and the border wasn't the same for all of them.
Now the borders of a table wrapper, table grid or table cell aren't
painted in collapsed borders mode. Instead, the resulting collapsed
borders are painted on their own.

`clientWidth` shouldn't include the borders of a box. The problem was
that we pretend that table wrapper boxes have the border specified on
the table element, even though this border actually applies to the
table grid box instead of the table wrapper box.
Therefore, `clientWidth` was wrong when it subtracted the borders.
This patch fixes it.

If an absolutely position element which is replaced has `justify-self`
or `align-self` set to `stretch`, and no inset is `auto` on that axis,
then an automatic size should behave as `stretch`, not as `fit-content`.

Some layouts like table need some style overrides. We were handling this
in `ComputedValuesExt`, but it was messy, unreliable and too limited.
For example, we were assuming that a style with `display: table` would
belong to a table wrapper box or table grid box. However, certain HTML
elements can ignore their `display` value and generate a different kind
of box. I think we aren't doing that yet, but we will need this.
Also, resolving the used border of a table needs layout information,
which we don't have in `ComputedValuesExt`. This patch will allow to
improve border collapsing in a follow-up.

We were previously using the same style and color for two collapsed
borders sharing a coordinate. Now such a line of collapsed borders can
be piecewise and have different colors and styles.
This still doesn't add support for piecewise border widths.
Also, since we are currently painting borders as part of the table and
cell boxes, and a box side can't have a piecewise border, this patch
only really works when:
- There aren't spanning cells
- The table has no assigned border (only the cells and tracks have it)
