Add UI for bypassing SSL handshake failures
There are several parts to these changes:
1. resurrecting the network error classification code to distinguish between SSL failures and other network errors
1. adding an SSL verification callback to support verifying certs against a list that can change at runtime, rather than just at program initialization
1. exposing a privileged chrome://allowcert URI which accepts the PEM cert contents along with a secret token
1. extracting the PEM cert contents out of the network layer when a handshake failure occurs, and getting them into the HTML that is parsed when an SSL failure occurs
1. adding a button in the handshake failure page that performs an XHR to chrome://allowcert with knowledge of the secret token and the PEM cert contents, before reloading the original URL that failed
The presence of the secret token means that while the chrome://allowcert URL is currently visible to web content, they cannot make use of it to inject arbitrary certs into the verification process.

Update webrender
These changes reflect changes in webrender's API that make RenderApiSender and RenderApi objects more challenging to share. This PR moves us to a model where:
* the compositor owns the main RenderApi object
* other threads that need to create transactions or manipulate fonts proxy those operations to the compositor (script/layout use IPC, while other threads use non-IPC channels)
* the webgl thread owns its own independent RenderApi
Update XHR send to use XMLHttpRequestBodyInit

Reduce scope of generic code in script
Combined, these changes account for almost 100k lines of generated code in a debug build for the script crate.

Prefix `on` for function name of inline events
While checking what needs to be done for the spec-update, I've noticed the logic of checking `is window-reflecting element (e.g. body and frameset)` is already handled by the `is` casting function.
However, we still failed to pass the tests because we're missing `on` prefix for inline functions.
I'm not sure if this patch is good enough (or maybe at least I need to add a comment for why adding `on` prefix?).
Besides, I checked [how Gecko handles](https://searchfox.org/mozilla-central/rev/8bc4e35c9bb47c1fe3131e6155d9f482e1efef9a/dom/events/EventListenerManager.cpp#1012-1022) and looks like they also just pass the atom directly.
But, the [generated atom](https://searchfox.org/mozilla-central/source/__GENERATED__/xpcom/ds/nsGkAtomList.h#775) is prefixed with `on` which is correct to just pass it into the `CompileFunction`.

Extract some of CGClassConstructHook to utils.rs
<!-- Please describe your changes on the following line: -->
Moving some of the functionality from the massive tripled quoted string in CGClassConstructHook in `components/script/dom/bindings/codegen/CodegenRust.py` to `components/script/dom/bindings/utils.rs`. Must be made unsafe because of UnwrapObjectDynamic and other functions. Added imports as necessary as well, as well as cleaning up using test-tidy.

We need to wait for #26699 to merge before this.

Improve precision of sequence types for WebIDL codegen.
Unlike #26699, this doesn't attempt to improve any of the resulting types and only maintains the status quo.

This is based on compiling with `RUSTFLAGS="-W unused_crate_dependencies"` (CC https://github.com/rust-lang/rust/pull/72342) in a recent Nightly (more so than used in the tree as of this writing, CC https://github.com/servo/servo/issues/26661 for work-arounds).
Only one crate is actually removed from the dependency graph, others are still dependended from other places.
