- Use `final` to indicate the classes that we actually
instantiate
- Properly use `const` (and the necessary associated `const_cast`
for zlib because we don’t define `ZLIB_CONST` and allow shared
builds)
- Store the JS callback in an internal field rather than a `Global`
(which improves memory leak debugging capabilities, removes
a potential future memory leak footgun, and aligns the code
with the rest of the codebase more closely)
- Other minor C++ cleanup

The presence of the inline definitions in node_internals.h can cause all
files that include node_internals.h to depend on util-inl.h, even if
they never use ThreadPoolWork. Whether this happens depends on the
toolchain, gcc will strip unused definitions, clang won't.

`v8::Global` is essentially a nicer variant of `node::Persistent` that,
in addition to reset-on-destroy, also implements move semantics.
This commit makes the necessary replacements, removes
`node::Persistent` and (now-)unnecessary inclusions of the
`node_persistent.h` header, and makes some of the functions that
take Persistents as arguments more generic so that they work with all
`v8::PersistentBase` flavours.

Create a class `PersistentToLocal` which contains three methods,
`Strong`, `Weak`, and `Default`:
* `Strong` returns a `Local` from a strong persistent reference,
* `Weak` returns a `Local` from a weak persistent reference, and
* `Default` decides based on `IsWeak()` which of the above two to call.
These replace `node::StrongPersistentToLocal()`,
`node::WeakPersistentToLocal()`, and `node::PersistentToLocal()`,
respectively.

Split out things that are specific to zlib as a specific
compression library, vs. the interface that is common to
most C compression libraries.
This should pave the way for including support for e.g.
brotli.

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 / `).

Split the existing `Write()` method into one that takes care
of translating the arguments from JS to C++, and a non-static
method for the actual write operations, as well as some minor
stylistic drive-by fixes.

- Use camel case names for memory retainers inherited from AsyncWrap
instead of their provider names (which are all in upper case)
- Assign class names to wraps so that they appear in the heap snapshot
as nodes with class names as node names. Previously some nodes are
named with reference names, which are supposed to be edge names
instead.

This will enable more detailed heap snapshots based on
a newer V8 API.
This commit itself is not tied to that API and could

Provide a custom memory allocator for zlib, and track
memory allocated by the library with it.
Right now this “only” makes reported external memory
usage (much) more accurate and protects against zlib
memory leaks, but it generally will enable us to give
more accurate memory usage statistics for zlib.
