There are at least benchmark types of cases where dispatching shadowrootattached all the time causes major performance hit.

Much like devtools manages the existing stylesheet changed events.
This is tested by devtools/client/inspector/markup/test/browser_markup_shadowdom.js

Fire shadowrootattached only if devtools is observing the document. r=smaug

Also enable the event on initialization.
