stylo: Improve restyling performance
This commit adds hooks to the Servo style traversal to avoid traversing all the
DOM for every restyle. Additionally it changes the behavior of the dirty flag to
be propagated top down, to prevent extra overhead when an element is dirtied.
This commit doesn't aim to change the behavior on Servo just yet, since Servo does extra job when dirtying the node related with DOM revision counters that might be necessary.
CC @asajeffrey for the DOM revision counters stuff. When a node is dirty, do all its descendants really need to increment the revision counter, or is this an unintended effect? My intuition is that this is hurting performance quite a lot for servo.

Pipeline lookup in webdriver
Fixes#11712
<!-- Please describe your changes on the following line: -->
Removed a method that seemed to duplicate already existing functionality, and returned BrowsingContextErrors in the web_handler file where panics were previously occurring.
I am not sure if I like all the unwrapping that occurs in the script thread, but the current methods are not set up to return Option/Result.
Also, should line the method on line 37 `find_node_by_unique_id` of components/script/webdriver_handlers.rs return None if the context is not found like I have it currently? Or should it return a `Result<Option...>` instead?

- [X] These changes fix#11712 .
<!-- Either: -->
- [ ] There are tests for these changes OR
- [X] These changes do not require tests because I simply removed a method that duplicated already existing functionality. On the other part, I added better error sending instead of forcing a panic, which does not require testing to my knowledge.

This is what was making me hit the new test failures. So turns out that when the
DOMContentLoaded event is fired we fired no messages to the constellation, but
we fired the DOMLoad message from the DocumentProgressHandler, effectively after
having dispatched the Load message from script thread.
This also fixes the possibility of a subframe navigation not blocking the load
event of the parent document, for example.

Implement non-visible pipeline and iframe visibility methods
This addresses #9566 and a good part of #9751, specifically:
* Pipeline has a notion of visibility
* IFrame setVisible/getVisible interface with IFrame's pipeline visibility
* IFrame mozbrowservisibilitychange responds to changes in visibility
* Pipeline visibility is used to limit animations (requestAnimationFrame does not tick animations when hidden) and to increase timer intervals (currently set to a minimum of 1 second while hidden)
Absent for now are any changes to the Document API and general implementation of the Page Visibility API, since the more interesting parts require knowledge of whether the user agent is minimized, OS screen locked, etc.

Make the net monitor panel in FF's devtools show meaningful output.
<!-- Please describe your changes on the following line: -->
1. Advertise support for the network monitor in the initial protocol communication.
1. Only notify the developer tools server about the final request in an HTTP transaction.
1. Add timing information for connecting to the HTTP server and sending the HTTP request.
1. Reduce duplication between various networkEventUpdate structures by creating a helper function
that merges two JSON structures together. This also corrects the JSON structure so the devtools
client interprets the output correctly.
1. Calculate various header size fields correctly.
1. Remove unnecessary usize->u32 casts by making the appropriate fields usize.
1. Add header values to request and response header messages.
1. Support triggering page reloads via the devtools client.
I apologize that these aren't broken apart. I was making a lot of changes trying to figure out why the panel wasn't working right, and a lot of them were tangled together.
