Implement trusted types for remaining attribute sinks (#38784)

Additionally, several methods were updated with
spec comments. That's because the "adopt the document
from the element document" step was missing.

By adding these spec comments, I also restructured
some code to avoid duplication of mutation records
and custom element reaction queueing.

Node.textContent doesn't propagate the error yet,
as that method has a lot of separate callers of
elements that wouldn't fail. I will refactor those
in a follow-up PR to keep things manageable.

This implements part of the DOM integration from
https://github.com/whatwg/dom/pull/1268

Part of #36258
