Attachment: Bug 1582374 - Add a warning when we find usage of the CSS zoom property.

Now that we count them, I think we should do this.

This property is pretty painful for various reasons:

• It's a pretty awkward non-standard property.
• Has a pretty short name, so people use it instead of the standard
  alternatives.
• We cannot really even implement it easily anyhow, without breaking a whole
  bunch of stuff, because pages do things like:

myelement {
  zoom: 0.5;
  -moz-transform: scale(0.5);
  transform-origin: 0 0;
}

For now this is only recorded when CSS use counters are enabled (Nightly for
now), but I want to change it once bug 1578661 is in central.
