Immutable CSSOM
This PR is intended to add basic support for all CSSOM interfaces, with the ability to index `document.styleSheets` and css rule lists, and serializing individual css rules. Handling individual interface methods for CSSRule subclasses can probably be done with easy/medium bugs.
Mutation safety isn't dealt with here; if the css rule list is mutated the CSSOM will be in an inconsistent state. I intend to deal with this via zero sized tokens, see https://groups.google.com/forum/#!topic/mozilla.dev.servo/AnxJoVmtMXQ . I'll handle that when I start making the CSSOM mutable. (Getting the immutable bit landed first opens this up for easy bugs)
This doesn't really change style aside from adding an extra arc in the CSS rule list as discussed in the linked thread. So far this same design can be used by stylo as well when the time comes.

Use rayon to drive parallel layout and styling.
<!-- Please describe your changes on the following line: -->
The current work queue had a really annoying constraint: The size of the node had to be the size of the work unit data.
This makes it impractical for the new restyling model where we plan to pass down a bunch of data.
Rayon by default makes you wait for the result of the work unit, which makes it impractical for the current model (it's mostly sequential).
I added an API to rayon that allows us to push work to the queue without waiting (https://github.com/nikomatsakis/rayon/pull/103).
This still needs some work (for example, we're loosing the memory reporting functionality), but I wanted feedback on this.

Minor fixes for the WebBluetooth implementation
<!-- Please describe your changes on the following line: -->
1. Fix for a comment typo in `bluetooth.rs `.
2. Simplify caling `self.request_bluetooth_devices` in `bluetooth.rs` in `Step 2`.
We already have a check in `Step 1` to prevent calling `request_bluetooth_devices` with a `Some` value if `option.acceptAllDevices` is true, and `option.filters` is already an `Option`, so there is no need for the `None` in the else branch.
3. Updating the bluetooth extension in `Navigator.webidl `, to match the [specification](https://webbluetoothcg.github.io/web-bluetooth/#navigator-extensions).
4. Replace the `_` separating the characteristic property strings with `-` as described [here](http://git.kernel.org/cgit/bluetooth/bluez.git/tree/doc/gatt-api.txt#n142)

This commit itself only moves things around and adds an extra parameter to the
`apply_declarations` function to eventually handle #14079 correctly.
Probably needs a more granular API to query fonts, á la nsFontMetrics, but
that's trivial to do once this is landed.
Then we should make the font provider mandatory, and implement the missing stylo
bits.

Return `KeyReaction::Nothing` for a Tab event
Do nothing instead of triggering the default action for a tab event.
Hitting the tab key in an html text input shouldn't submit the form, and for any text input, the tab key should have a particular action associated, not the default action.
This cleans up #12701.
