src: use effective cppgc wrapper id to deduce non-cppgc id #48660

deps: V8: cherry-pick 93275031284c

Original commit message:

[cppgc] expose wrapper descriptor on CppHeap

This makes it possible for embedders to:

1. Avoid creating wrapper objects that happen to have a layout that
  leads V8 to consider the object cppgc-managed while it's not.
  Refs: https://github.com/nodejs/node/pull/43521
2. Create cppgc-managed wrapper objects when they do not own the
   CppHeap. Refs: https://github.com/nodejs/node/pull/45704

src: use effective cppgc wrapper id to deduce non-cppgc id

Previously we hard-code a wrapper id to be used in BaseObjects
to avoid accidentally triggering cppgc on these non-cppgc-managed
objects, but hard-coding can be be hacky and result in mismatch
when we start to create CppHeap ourselves. This patch makes it
more robust by deducing non-cppgc id from the effective cppgc id,
if there is one.

The V8 cherry-pick should have also bumped v8_embedder_string in common.gypi.

@richardlau Thanks for catching it, it probably happened because I created the backport commit before ce4102e landed. I've amended the first commit.

Looks like there is a build error in our build machine, perhaps depot_tools is out of date ?

This patch: - Initializes cppgc in InitializeOncePerProcess() when kNoInitializeCppgc is not set - Create a CppHeap and attach it to the Isolate when there isn't one already during IsolateData initialization. The CppHeap is detached and terminated when IsolateData is freed. - Publishes the cppgc headers in the tarball. This allows C++ addons to start using cppgc to manage objects. A helper node::SetCppgcReference() is also added to help addons enable cppgc tracing in a user-defined object.
