This makes sure that the tests are run on actual heap snapshots
and prints out missing paths when it cannot be found, which
makes failures easier to debug, and removes the unnecessary
requirement for BaseObjects to be root - which would make
the heap snapshot containment view rather noisy and is not
conceptually correct, since they are actually held by the
BaseObjectList held by the realms.

This patch adds helpers for wrapper classes based on cppgc (Oilpan)
in `src/cppgc_helpers.h`, including `node::CppgcMixin` and
`ASSIGN_OR_RETURN_UNWRAP_CPPGC`, which are designed to have
similar interface to BaseObject helpers to help migration.
They are documented in the `CppgcMixin` section in `src/README.md`
To disambiguate, the global `node::Unwrap<>` has now been moved
as `node::BaseObject::Unwrap<>`, and `node::Cppgc::Unwrap<>`
implements a similar unwrapping mechanism for cppgc-managed
wrappers.

This allows us to mark weak/detached references in the heap snapshot.
Also mark weak/detached BaseObject with Detachedness::kDetached
so that the state of the reference can be displayed by frontend
consuming the heap snapshot.

This patch:
- Refactors the `MemoryRetainer` API so that the impementer no longer
calls `TrackThis()` that sets the size of node on the top of the
stack, which may be hard to understand. Instead now they implements
`SelfSize()` to provide their self sizes. Also documents
the API in the header.
- Refactors `MemoryTracker` so it calls `MemoryInfoName()` and
`SelfSize()` of `MemoryRetainer` to retrieve info about them, and
separate `node_names` and `edge_names` so the edges can be properly
named with reference names and the nodes can be named with class
names. (Previously the nodes are named with reference names while the
edges are all indexed and appear as array elements).
- Adds `SET_MEMORY_INFO_NAME()`, `SET_SELF_SIZE()` and
`SET_NO_MEMORY_INFO()` convenience macros
- Fixes a few `MemoryInfo` calls in some `MemoryRetainers` to track
their references properly.
- Refactors the heapdump tests to check both node names and edge names,
distinguishing between wrapped JS nodes (without prefixes)
and embedder wrappers (prefixed with `Node / `).
