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.

Typically, block-level contents are stacked vertically, so this was just
taking the maximum size among all contents. However, floats can be
stacked horizontally, so we need to sum their sizes.
… and converting them to flow-relative geometric values.
These values are almost always used to size and position a fragment within its containing block, so using the mode of the containing block seems more correct.
Note that the `writing-mode` and `direction` properties are disabled in Servo at the moment, so this PR by itself should have no effect: the writing mode of an element is always the same of that of its containing block since they’re both horizontal rtl.
