We have the right conversions to make this work, so let's make it
possible to have a `HashMap<JS::Handle<T>, V>` and look for a specific
T inside it without having to create a temporary handle.
This involves adding some operator== implementations, and some
specializations of AK::Traits.
Even if the pointer value is const, the value they point to is not
necessarily const, so these functions should not add the qualifier.
This also removes the redundant non-const implementations of these
operators.
This was previously indirectly forcing Heap/Handle.h to include it
instead. This will let us include Handle.h from PropertyKey, which will
allow us to solve a different issue.
Previously this would've said `make_handle(Value(1234))` is null, as it
did not contain a cell (but rather a plain Value), which made throwing
primitives spin forever in BC mode.
This allows you to keep an arbitrary JS::Value alive without having to
hook visit_edges somewhere, e.g. by being a NativeFunction that
overrides visit_edges.
For example, this allows you to store JS::Handle<JS::Value> as the key
of a HashMap. This will be used to keep arbitrary Values alive in
the key of a temporary HashMap in Array.prototype.groupByToMap.
