Emilio Cobos Álvarez a7401488af Bug 1784265 - Drop support for flex attribute values other than 0 and 1. r=dholbert,mconley,preferences-reviewers
This makes it easier to get parity between legacy and regular flex
without having to either have tons of arbitrary attribute selectors in
the xul sheet, nor adding attribute lookup hacks to the html flexbox
layout.

Also, reimplement the remaining supported flex attribute-values (0 and 1)
purely in terms of CSS rules in xul.css (regardless of whether
emulate-moz-box-with-flex is enabled).

In practice these are pretty uncommon and the style attribute does the
trick in every case I've tried.

Add a debug-only assertion to ensure we preserve behavior for now.

Add a new test with another behavior difference between flexbox
emulation and old xul layout because the old reftest now passes. Use
replaced elements, which in modern flex are treated differently.
