Avoid killing the whole mutable state in the following two cases:
- When we encounter a mutable object store operation, we can only kill
  the respective object/field pair in the mutable state.
- When we encounter an immutable initialization operation, we do not
  have to modify the state. A DCHECK ensures we do not initialize the
  same field twice.

Drive-by: Avoid zone-allocating data structures for frame-local
variables.

Handle the case of nested super() by checking if the class scope
contains a private brand. In this case the ContextScope chain
is different from the actual context chain so this added back
the AddPrivateBrand() runtime function but with the additional
step of walking the context chain to get the correct class
context that will be stored as the value of the brand property
for the debugger.

We need to create the CodePageCollectionMemoryModificationScope *after*
setting up the LocalIsolate. Otherwise the destructor of that scope will
run after that thread detached from the isolate, when it isn't part of
the next GC safepoint anymore. This allows two concurrent operations
on the page flags:

1) The destructor of CodePageCollectionMemoryModificationScope protects
   the page again and accesses page flags in a DCHECK.
2) The GC unprotects the code pages for the collection and sets the
   the evacuation candidate flag.

--shared-string-table assumes that all old strings are in the shared
heap. However, when also using --expose-gc we create an external string
for the GC function name. So far external strings are always allocated
in the local old space though, which results in a heap verification
error. This CL creates external string in the shared old heap with
--shared-string-table enabled.

In order to pass all the tests this CL also has to:

* Stop marking into the shared heap for VisitEmbeddedPointer and
  VisitCodePointer.
* Relax DCHECK in String::GetFlatContent: We cannot check the thread
  id for any shared string. Even if that string isn't really shared atm.

When the debugger is active and a Promise begins executing,
Isolate::PushPromise adds a global handle for that Promise. If the
debugger is no longer attached when the Promise finishes executing, then
there is no corresponding call to PopPromise which would clean up the
global handle. To avoid leaking memory in that case, we should clean up
the Promise stack when detaching the debugger.

- Unroll loop in ReadVarInt to skip checks for uncommon branches and
  improve by ~15%
- Use cage_base more aggressively
- Use more dehandlified code if possible
- Allow allocating strings directly in old-space to avoid filling up the
  new space when deserialising web-snapshots

Cleanup:
- ThrowDataCloneError now returns Nothing<bool>() for more consistency

Not all environments (like ShadowRealm) would expect console
APIs to present in their globals. Moving console API to
context's extras binding to allow them to be still
snapshotted to not slow down the bootstrap.

The console API is not removed from the global in this CL,
but it is planned to be removed in the later release.
