Update declarative Shadow DOM opt-in mechanics

The issue thread [1] has had more discussion, after the initial draft
of declarative Shadow DOM opt-in landed [2]. This CL implements those
bits of feedback. In particular:

• There is no public allowDeclarativeShadowDom state available on
  Document or DocumentFragment.
• All APIs use call parameters to avoid state, with the exception
  of DOMParser.
• innerHTML no longer supports Declarative Shadow DOM.
• A new setInnerHTML() function allows opt-in access to DSD.
• Several of the more obscure APIs do not have an opt-in for
  declarative Shadow DOM, such as XHR, createContextualFragment, and
  document.write.
• The sandbox flag has been removed from iframes completely. The new
  plan is to use DocumentPolicy to enable declarative Shadow DOM for
  iframes. For now, iframes do not support declarative Shadow DOM.
• allowDeclarativeShadowDOM has become allowShadowRoot.
