Andreas Kling 12ac6861e3 LibWeb: Improve how layout nodes decide whether they have definite sizes ...

1. Make this decision *after* we've inserted the layout node into the
   layout tree. Otherwise, we can't reach its containing block!
2. Per css-sizing-3, consider auto-sized blocks whose sizes resolve
   solely against other definite sizes as definite themselves.

In particular, (2) makes us consider width:auto block children of a
definite-size containing block as having definite size. This becomes
very important in flex layout.
