Prevent infinite recursion when upgrading custom elements
<!-- Please describe your changes on the following line: -->
The spec and tests were out of sync when I implemented #25410 and I mentioned I'd have an extra detail to attend to if whatwg/html#5126 landed; it did, and I did, and a couple test cases pass.

Implement HTMLMenuElement
<!-- Please describe your changes on the following line: -->
Per spec, "The menu element is simply a semantic alternative to ul to express an unordered list of commands (a "toolbar")." We already have the CSS for it in user-agent.css, and this gives us the interface object.

Add microtask checkpoints to script elements and custom elements
Servo had a microtask checkpoint at the end of running a script, but there was also supposed to be one at the end of HTML-parsing a script element before Javascript-parsing the script itself, and there were supposed to be checkpoints immediately after the call to a custom element constructor. This adds those, passing all cases of one WPT test file.

Refactor promise compartment
<!-- Please describe your changes on the following line: -->
This PR adds a mechanism to verify that certain code is executed inside a ```JSAutoCompartment```, and applies this to the ```Promise::new_in_current_compartment``` constructor.

Servo currently uses `heapsize`, but Stylo/Gecko use `malloc_size_of`.
`malloc_size_of` is better -- it handles various cases that `heapsize` does not
-- so this patch changes Servo to use `malloc_size_of`.
This patch makes the following changes to the `malloc_size_of` crate.
- Adds `MallocSizeOf` trait implementations for numerous types, some built-in
(e.g. `VecDeque`), some external and Servo-only (e.g. `string_cache`).
- Makes `enclosing_size_of_op` optional, because vanilla jemalloc doesn't
support that operation.
- For `HashSet`/`HashMap`, falls back to a computed estimate when
`enclosing_size_of_op` isn't available.
- Adds an extern "C" `malloc_size_of` function that does the actual heap
measurement; this is based on the same functions from the `heapsize` crate.
This patch makes the following changes elsewhere.
- Converts all the uses of `heapsize` to instead use `malloc_size_of`.
- Disables the "heapsize"/"heap_size" feature for the external crates that
provide it.
- Removes the `HeapSizeOf` implementation from `hashglobe`.
- Adds `ignore` annotations to a few `Rc`/`Arc`, because `malloc_size_of`
doesn't derive those types, unlike `heapsize`.
Fixes warnings from rust-lang/rust#44229 when `--enable-commonmark` is
passed to rustdoc.
This is mostly a global find-and-replace for bare URIs on lines by
themselves in doc comments.
