* Add `no_trace` option to JSTraceable derive * NoTrace wrapper * Port some types to no_trace schematics * Fixing my unsafe mistakes (not tracing traceables) * Add docs & safety guards for no_trace Safety guards (trait shenanigans) guarantees safety usage of `no_trace` * Port canvas_traits to no_trace * Port servo_media to no_trace * Port net_traits to no_trace * Port style to no_trace * Port webgpu to no_trace * Port script_traits to no_trace * Port canvas_traits, devtools_traits, embedder_traits, profile_traits to no_trace * unrooted_must_root lint in seperate file * Add trace_in_no_trace_lint as script_plugin * Composable types in must_not_have_traceable * Introduced HashMapTracedValues wrapper * `HashMap<NoTrace<K>,V>`->`HashMapTracedValues<K,V>` * Port rest of servo's types to no_trace * Port html5ever, euclid, mime and http to no_trace * Port remaining externals to no_trace * Port webxr and Arc<Mutex<_>> * Fix spelling in notrace doc
