Add &DomRoot<T> lint check

So far, the lint check code appears to work as intended. However, some trait implementations require modification to pass the lint check and I'm not sure how to fix these. Commit 92cf5d5 attempts to correct one of the implementations, but fails to compile with error:
```
  --> components/script/dom/servoparser/xml.rs:76:36
   |
76 |         tree_builder.trace_handles(&tracer);
   |                                    ^^^^^^^ expected struct `dom::bindings::root::Dom`, found struct `dom::node::Node`
   |
   = note: expected struct `dom::bindings::root::Dom<dom::node::Node>`
              found struct `dom::node::Node`
   = note: required for the cast to the object type `dyn html5ever::tree_builder::Tracer<Handle = dom::bindings::root::Dom<dom::node::Node>>`
```
I've tried to debug further but to no avail. I also don't want to mangle too much existing code unnecessarily. Any help is appreciated.
