A box is usually sized by the formatting context in which it participates.
However, tables have some special sizing behaviors, and these were in
conflict.
Instead of letting tables attempting to re-resolve their inline table,
which failed to e.g. take flex properties into account or resolve sizing
keywords correctly, now tables will trust the inline size determined by
the parent. They will only floor it by the min-content size, and maybe
shrink the final size due to collapsed columns.

* layout: Take into account `display: table` etc in offset* queries
The specification says that for deciding whether an element should be
used for offset* queries, a browser should take into account whether the
element is a table cell or table. This change makes that happen.

This change adds a version of row height distribution that follows the
distribtuion algorithm used for tables in Blink's LayoutNG. This is just
an intermediate step toward implementing a distribution algorithm for
both rows and columns more similar to Layout NG.
The CSS Table 3 specification is often wrong with regard to web
compatability, which is why we have abandoned it in favor of the Layout
NG algorithm for row height distribution. this work.

This adds support for table rows, columns, rowgroups and colgroups.
There are few additions here:
1. The createion of fragments, which allows script queries and hit
testing to work properly. These fragments are empty as all cells are
still direct descendants of the table fragment.
2. Properly handling size information from tracks and track groups as
well as frustrating rules about reordering rowgroups.
3. Painting a background seemlessly across track groups and groups. This
is a thing that isn't done in legacy layout (nor WebKit)!

* layout: Implement computation of table column widths
This change implements the various steps of table column width
computation, ignoring features that don't exist yet (such as separated
borders, column elements, and colgroups).

* layout: Add *very* basic support for table layout
This is the first step to proper table layout. It implements a naive
layout algorithm, notably only taking into account the preferred widths
of the first table row. Still, it causes some float tests to start
passing, so turn on the `layout.tables.enabled` preference for those
directories.
