[css-values-5 calc-size()] Implement interpolate-size
https://bugs.webkit.org/show_bug.cgi?id=324460
rdar://187701518
Reviewed by Alan Baradlay.
https://drafts.csswg.org/css-values-5/#interpolate-size
With "interpolate-size: allow-keywords" keyword valued size properties can
transition with other values
height: 0px; -> height: max-content;
without using calc-size() explicitly. Internally this is implemented as
calc-size() interpolation.
The patch also removes an incorrect blending shortcut that artificially made
some tests pass.
Per spec calc-size() interpolation needs to also happen at 0 and 1 end points.
The tests will
start passing when the relevant layout bits are implemented.

These enumerate every property, so a new one shifts their counts.
