Bug 1839223 - Remove nsMappedAttributes. r=smaug 

Instead, lazily schedule evaluation of them before styling, much like we
were doing for SVG.

A subtle tweak is that we only remain scheduled while in the document.
This allows us to use the "in document" bit plus the "mapped attributes
dirty" bit to know our scheduled status. It also prevents doing silly
work for disconnected elements, and having to do hashmap lookups on
adoption and node destruction.
