Fix column and row measures (#31480)

The min-content size of a table track was >= the max-content size. So
- For the min-content size of a column, now we just use min-inline-size,
  ignoring inline-size and max-inline-size. This matches Gecko, Blink
  and WebKit.
- For the max-content size of a column, we keep matching Gecko.
  Note that Blink and WebKit are different, they ignore max-inline-size.
- For both the min-content and max-content sizes of a row, now we just
  use block-size. This matches Gecko, Blink and WebKit.

Also, if the computed value contains percentages, now we treat it as
the initial value, instead of resolving percentages against zero.
This matches Gecko and Blink, but not WebKit for rows.
