Implement dom exception constructor
The constructor method was implemented
I have a question: should I edit `./mach test-wpt` expectations?

#8539 Config preferences backend restructure
<!-- Please describe your changes on the following line: -->
A procedural macro for generating static structures for use as the backend for config preferences, as well a mapping from string names to accessors.
Preferences can be accessed and updated via a map-like interface with `String` keys, and now also via a convenience macro: `get_pref!(path.to.pref)`. Various `serde`-compatible field attributes are also supported, including renaming the string keys. This could be useful when changing the backend structure without breaking existing usages.
I have added the choice to use `i64` as well as `f64` for storing numbers. As it turns out, none of the existing preferences used non-integer values. Setting a floating point value from a command-line argument requires a decimal point in order to parse correctly.

I have a few outstanding problems or questions:
1. I am unable to get rid of this warning:
```
warning: unnecessary path disambiguator
--> components/config/prefs.rs:130:51
|
130 | accessor_type = crate::pref_util::Accessor::<Prefs, crate::pref_util::PrefValue>,
| ^^ try removing `::`
```
See: https://stackoverflow.com/questions/54710797/how-to-disable-unnecessary-path-disambiguator-warning
2. Several of the preferences in use were not represented in `prefs.json`. Some of these may be in error, but it is hard to tell. For example `js.offthread_compilation.enabled` vs `js.ion.offthread_compilation.enabled` could be different preferences or could be intended to have the same value.
3. Previously, several pieces of code provided default values when accessing a preference that may not be present. For example:
```Rust
let DBL_CLICK_TIMEOUT = Duration::from_millis(
PREFS
.get("dom.document.dblclick_timeout")
.as_u64()
.unwrap_or(300),
);
```
Fallback values don't really make sense now and I've added these defaults to `prefs.json`. Does this sound right?
4. I have kept `PrefValue::Missing`, though it doesn't seem very useful any more. An error might be more appropriate now for an incorrect preference key. I've kept this partly because [`webdriver_server` uses it](https://github.com/servo/servo/blob/master/components/webdriver_server/lib.rs#L224).

Update webdriver crate
<!-- Please describe your changes on the following line: -->
I was playing around with the WebDriver tests and I managed to get some of them pass (several tests in `new_session/default_values.py`) by updating the `webdriver` crate to the latest version. It looks like the fix of this bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1507428 made the tests pass.

Assert fail #18439
<!-- Please describe your changes on the following line: -->
This PR addresses #18439 by removing an assert statement that forces a panic whenever `LoadBlocker` is dropped during a GC sweep and receives a `None` `SCRIPT_THREAD_ROOT` value from `mark_document_with_no_blocked_loads()`. Instead of panicking on the assert, we remove it and let the None value pass silently.

Add Gecko reftests, which are failing with gfx-hal backend
<!-- Please describe your changes on the following line: -->
Since the focus of the Szeged team will shift to Servo from Gecko, we would like to add some reftests from Gecko which are failing with the gfx-rs backend.
Last year we had pretty good results with Servo css tests: https://github.com/szeged/webrender/issues/173#issuecomment-415373702.
On the Gecko side we had more failing tests, and it would be nice to have a subset of those in Servo, even tough some of them fails on the Servo side.
