Instead of unwrapping `new_with_jsobject` result, `ImageData::new` will just pass the error along.
It required tweaking `canvasrenderingcontext2d` as it no longer needs to assume the result is `Ok`.

Before this PR, every object reflected in CSSOM is in `Arc<RwLock<_>>` to enable safe (synchronized) mutable aliasing. Acquiring all these locks has significant cost during selector matching:
* https://bugzilla.mozilla.org/show_bug.cgi?id=1311469
* https://bugzilla.mozilla.org/show_bug.cgi?id=1335941
* https://bugzilla.mozilla.org/show_bug.cgi?id=1339703
This PR introduce a mechanism to protect many objects with the same `RwLock` that only needs to be acquired once.
In Stylo, there is one such lock per process (in a `lazy_static`), used for everything.
I non-Stylo Servo, I originally intended to have one such lock per document (for author-origin stylesheets, and one per process for user-agent and user sytlesheets since they’re shared across documents, and never mutated anyway). However I failed to have the same document-specific (or pipeline-specific) `Arc` reachable from both `Document` nodes and `LayoutThread`. Recursively following callers lead me to include this `Arc` in `UnprivilegedPipelineContent`, but that needs to be serializable. So there is a second process-wide lock.
This was previously #15998, closed accidentally.

I think these properties are generally rare enough that they're not worth adding 8 bytes of memmove overhead on every PropertyDeclaration. There are a _lot_ of 24-byte properties though, so I think that's probably a good sustainable level.

Current browsing context accessor in `Document` unwraps the browsing context `Option` which prevents document to handle correctly the case when there is no browsing context.
This is the reason servo panics with `session-history.max-length=1` (https://github.com/servo/servo/issues/15877).
As it is my first contribution, I added a `safe` method to retrieve the browsing context rather than change the existing method, but I am happy to change if you think this is the right approach. I did not as well replace all existing method call to the `safe` method, to focus on fixing the issue.
If someone can give me a bit of guidance for the test, I will try to contribute one.

The design of initiating network requests from the image cache thread was simple, but it makes it difficult to implement image loading that conforms to the HTML specification. These changes make the implementation of HTMLImageElement responsible for network requests for `<img>` elements, and CSS-based images (background-image, bullets, etc.) are requested by the script thread to ensure that the layout thread does not attempt to retain unsafe pointers to DOM nodes during asynchronous operations.
