0d827da34d cppgc: Add more basic type traits
Adds traits for checking for Member,WeakMember, and UntracedMember
types.

This allows the embedder to specify its own traits and restrictions

c9e883e803 (Step 1 of 2): Prepping Wasm events in the Recorder interface
As part of an effort to prepare the Recorder interface for general use,
we had to make some changes to the way the existing Wasm Events are
being used. In particular,
  - it is more fitting to use a ElapsedTimer than a TimedScope to
    measure the durations in src/wasm/module-[decoder|instantiate].cc
  - we want to rename the wall_clock_time_in_us field to duration_in_us
    for clarity.

Because these Wasm events are already being instantiated in chromium,
renaming the field requires a two-step change. This is the first of
those changes.

2ccd4dc564 Introduce Function::FunctionProtoToString()
Add a new function on the public API to allow serializing a function to
a string using the built-in toString() implementation, allowing
serialization without worrying about untrusted author script overriding
the toString() implementation. This is similar in nature to
Object::ObjectProtoToString() (but that only returns "[object Function]"
for any passed function).

Add tests for the same.

543e5633af [api] TC39 Dynamic Code Brand checks - rename for consistency.
Rename-only CL: Rename "code kind" to "code like".

The reason is CL feedback when using this feature, and a desire for
consistency across V8 + Blink. An additional benefit would be to
disambiguate from the v8::internal::CodeKind type, which is unrelated to
any of this.

9a49b2298f Fix alloc/dealloc size mismatch for v8::BackingStore
On newer compilers the {operator delete} with explicit {size_t}
argument would be instantiated for {v8::BackingStore} and used
in the destructor of {std::unique_ptr<v8::BackingStore>}. The {size_t}
argument is wrong though, since the pointer actually points
to a {v8::internal::BackingStore} object.
The solution is to explicitly provide a {operator delete}, preventing
an implicitly generated {size_t} operator.

5720d2056c [regexp] Add 'l' flag to force experimental engine
This commit adds the 'l' (linear) RegExp flag (as in e.g. /asdf|123/l)
that forces execution in linear time.  These regexps are handled by the
experimental engine.  If the experimental engine cannot handle the
pattern, an exception is thrown on creation of the regexp.

The commit also adds a new global V8 flag and changes an existing one:
* --enable-experimental-engine, which turns on recognition of the RegExp
  'l' flag.  Previously this flag also caused all supported regexps to
  be executed by the experimental engine; this is not the case anymore.
* --default-to-experimental-regexp-engine takes over the previous
  semantics of --enable-experimental-regexp-engine:  We execute all
  supported regexps with the experimental engine.

954b3a7787 Prepare for moving object description generation to blink (ValueMirror)
This CL is a preliminary work to move the description generation of objects that are not V8 specific to the Embedder. Until now, the description for Nodes and Trusted Types was generated by V8 what was problematic, since Blink (not V8) is who has access to the information required for the description.
Once the refactoring is complete the existing descriptionForNode and descriptionForTrustedType can be deleted from V8.

aa42907747 heap, cpppgc: Add support for wrappper nodes in snapshots
Wrapper nodes are merged into their corresponding C++ object nodes
when the reference between C++ and JS object has a wrapper class id
set.

Instead of iterating all global handles and checking for those with
class ids, the new algorithm discovers them while iterating C++
objects.

Note: Additional wrapper nodes, e.g., those from isolated worlds in
Blink are not merged.

This CL ports the existing backing store compaction algorithm from
blink. It does not attempt to improve on the existing algorithm.

Currently only unified heap uses the compaction implementation. It is
never triggered through standalone GCs.

The compaction implementation resides within an internal "subtle" namespace.

4569ffae0b Migrate CrossThreadPersistent
Adds a cross-thread reference for strongly and weakly retaining
objects on a thread other than the thread that owns the object.

The intended use of the reference is by setting it up on the
originating thread, holding the object alive from another thread, and
ultimately accessing the object again on the originating thread.

The reference has known caveats:
- It's unsafe to use when the heap may terminate;
- It's unsafe to transitively reach through the graph because of
  compaction;
