Adds support for parsing top level await to V8, as well as
many tests.
This is the final cl in the series to add support for top level
await to v8.

This cl adds support for top level await to d8, but still
does not allow top level await through parsing.
Unfortunately, due to that restriction this cl has no automated
tests, but I added a 'top-level-await' variant and manually
confirmed it passes locally.

This patch uses a bit in the Variable bit fields to distinguish
static private names from instance private names, so that we
can check the conflicts of private accessors that are complementary
but with different staticness in the parser, and use this
information later when generating code for checking static brands
for private method access.

Expressions in class heritage position do not have access to the
inheriting class's private names, only its lexical bindings. The parser
currently uses the same scope chain for both.
This CL makes scopes in class heritage position skip their outer class
when resolving private names. Whether a scope needs to skip is kept as a
bit on various scope-related data structures.

This patch implements the declaration of private accessors.
When iterating over the class properties, we track private
accessors associated with the same name in a ZoneHashMap.
Once we get to all the necessary components for a private name
(we know statically whether we should expect only a setter,
only a getter, or both), we emit a call to a runtime function
`CreatePrivateAccessors` that creates an AccessorPair, and
store the components in it. The AccessorPair is then associated
with the private name variable and stored in the context
for later retrieval when the private accessors are accessed.

This patch adds:

- VariableMode::kPrivateSetterOnly
- VariableMode::kPrivateGetterOnly
- VariableMode::kPrivateGetterAndSetter
And replace the previous RequiresBrandCheckFlag by inferring
whether the brand check is required from these VariableModes.
It is then possible to check duplicate non-complementary
accessors in the parsers and throw early errors, and allow
complementary accessors to be associated with the same
private name variable.
This patch also adds the following AssignType:
- PRIVATE_METHOD
- PRIVATE_GETTER_ONLY
- PRIVATE_SETTER_ONLY
- PRIVATE_GETTER_AND_SETTER
corresponding to the new VariableModes so that it's possible
to generate specialized code for different type of
private accessor declarations.

Previously, this was run as a microtask and this CL changes it to run
as a separate task as mandated by the current WeakRef spec.
This CL also introduces a FinalizationGroup type to the V8 API
representing the JSFinalizationGroup. This has a `Cleanup`
function that runs the cleanup callback associated with it.
SetHostCleanupFinalizationGroupCallback is added to set
the embedder defined HostCleanupFinalizationGroupCallback.
ClearKeptObject is exposed on the v8::Isolate to reset the strongly
held set of objects.
The general workflow is the following:
(a) When the GC notices that a given finalization group has dirty
cells, it calls HostCleanupFinalizationGroupCallback with the given
finalization group.
(b) As part of HostCleanupFinalizationGroupCallback, the embedder
enqueues a task that at some point later calls
FinalizationGroup::Cleanup.
(c) At some point in the future, FinalizationGroup::Cleanup is called,
which runs the cleanup callback of the finalization group.
This patch also includes d8 changes to use these new APIs. Currently,
d8 cycles through the enqueued finalization groups after a synchronous
turn (and it's microtask checkpoint) and runs the cleanup callbacks.

This change implements lowering of speculative BigInt addition as well as
BigInt heap constants to corresponding int64 versions, if they are used in
a context where the result is truncated to the least significant 64 bits
(e.g. using asUintN). The JSHeapBroker is extended to provide access to the
BigInt's least significant digit during concurrent compilation. The BigInt
context (required to introduce correct conversions) is recognized in the
RepresentationChanger by either the output type propagated downward or the
TypeCheckKind propagated upward. This is necessary, because the TypeCheckKind
may only be set by nodes that may potentially deopt (and sit in the effect
chain). This is the case for SpeculativeBigIntAdd, but not for BigIntAsUintN.
This CL contains a simple fix to prevent int64-lowered BigInts to flow into
state values as the deoptimizer cannot handle them yet. A more sophisticated
solution to allow the deoptimizer to materialize truncated BigInts will be
added in a following CL.

This patch implements the declarations of private methods, the access
of private methods would be left to a future patch.
When a private methods declaration is encountered, we now:
- Create a brand symbol during class evaluation and store it in the
context.
- Create the closures for the private methods
- Load the brand from the context and store it in the instance in the
constructor.

MicrotaskQueue associated to Context may be null after DetachGlobal,
and triggering FinalizationGroup clean up on the detached context
causes a crash.
This CL fixes the crash by cancelling the clean up on such a context.

Previously when an unresolved private name is not found
in the current scope but found in an outer class scope,
we forget to push it to the outer class scope so the
name would never get bound.
This patch simplifies ClassScope::ResolvePrivateNamesPartially()
and removes the search in outer class scopes since they are incomplete
at this point. Instead just push any private name that can't be
resolved in the current scope to the outer class scope so that it
gets handled later when the outer class scope is complete.

These tests make sure the ticks are correct when resolving against a
Promise.
Without the optimization, the result is:
"start,tick 1,tick 2,tick 3,tick 4,done,tick 5"
With the optimization, the result is:
