There are two flavours of the mozjs `TypedArray<T>` wrapper for typed
array objects: one stores a `Box<Heap<*mut JSObject>>`, while the other
just has a bare `*mut JSObject`. The second one must only be stored
inside the `CustomAutoRoot` rooting values, but we were using it in many
other places like WebIDL dictionaries without rooting it safely. These
changes make our typed array APIs always use
`RootedTraceableBox<TypedArray<T>>` with the `Box<Heap<*mut JSObject>>`
flavour, which ensures that the JS object stored inside the typed array
wrapper is always visible to the SpiderMonkey GC.
Testing: Adds a new test that crashes without these changes.

This implements LazyDOMString (from now on DOMString) as outlined in
https://github.com/servo/servo/issues/39479.
Constructing from a *mut JSString we keep the in a
RootedTraceableBox<Heap<*mut JSString>> and transform
the string into a rust string if necessary via the `make_rust_string`
method.
Methods used in script are implemented on this string. Currently we
transform the string at all times.
But in the future more efficient implementations are possible.
We implement the safety critical sections in a separate module
DOMStringInner which allows simple constructors, `make_rust_string` and
the `bytes` method.
This method returns the new type `EncodedBytes` which contains the
reference to the underlying string in either format.
Testing: WPT tests still seem to work, so this should test this
functionality.

This updates all Rc that were ignored for malloc_size_of to use
conditional_malloc_size_of, unless the type in the Rc itself doesn't
support malloc_size.
Regular expressions used to search for all occurrences:
```
ignore_malloc_size_of = "Rc.*"
ignore_malloc_size_of = "Arc.*"
```
There are a couple left since they have nested Rc, which I don't know
how to fix.
To be able to define these, several new implementations were added to
`malloc_size_of/lib.rs` as well as
`HashMapTracedValues`.
Testing: if it compiles, it's safe

Move testbinding interfaces to it's own module, to avoid cluttering dom
folder.
Testing: A successful build is enough
