Emilio Cobos Álvarez 597b7bc37d Bug 1729330 - Add a simple CSSLayerRule implementation. r=smaug
The specifics of how this is going to work are still getting spec'd /
discussed in https://github.com/w3c/csswg-drafts/issues/6576, but this
allows DevTools to work fine and the feature to be complete enough for
Nightly experimentation (with the other in-flight patches).

Otherwise devtools crashes when trying to inspect pages that use them.
