- In DeserializeContext, scope info local values
snapshot is in order of `name,value,name,value`,
and we should ReadValue after ReadString.

- Support non-inlined ScopeInfo locals, use
NameToIndexHashTable to serialize and deserialize
scope info local values when its local count is
more than kScopeInfoMaxInlinedLocalNamesSize.

One of the biggest categories in heap snapshots is named “(system)”,
which gives developers no indication of why all that memory is used or
what they might do to reduce it. In this change, I propose that we
create a new category for Maps, DescriptorArrays, and related objects,
and call this new category “(object shape)” in the devtools. I think
that this category name would be more meaningful, while still grouping
those objects together so that they mostly stay out of the way.

RegisterFrameState is a container for free registers and values.
It abstracts operations for GeneralRegisters and DoubleRegisters.

It will be used later to call generic functions from the allocator,
depending on the register type needed.
See PrintLiveRegs as an example of function reuse.

As per https://tc39.es/ecma262/#sec-hostimportmoduledynamically defined,
referencingScriptOrModule in HostImportModuleDynamically can be a Script
Record, a Module Record, or null.
So to https://tc39.es/proposal-shadowrealm/#sec-shadowrealmimportvalue,
the HostImportModuleDynamicallyCallback is been invoked with a `null`
resource_name. This may not be considered a breaking change as the
parameter resource_name is defined as Local<Value>.

Updates d8's DoHostImportModuleDynamically to handle null resource_name,
and resolve the dynamically imported specifier relative to the executing
script's origin. In this way, we have to set ModuleEmbedderData.origin
even if the JavaScript source to be evaluated is Script. Also, a
ModuleEmbedderData is created for each ShadowRealm to separate their
module maps from the initiator context's.

This CL extends GetIterator to check whether the result of
calling @@iterator is JSReceiver and throw SymbolIteratorInvalid
if it's not JSReceiver.

GetIterator bytecode involves 3 steps now:
- method = GetMethod(obj, @@iterator)
- iterator = Call(method, obj)
- if(!IsJSReceiver(iterator)) throw SymbolIteratorInvalid [Added]

New Builtin: CallIteratorWithFeedbackLazyDeoptContinuation, which
is used when lazy deopt is triggered by call @@iterator.

Since the TLS offset is constant across all supported OS releases, we
no longer need to adjust it, nor to read it at runtime. This also aligns
the code in V8 with what is done in Chromium.

Normally, taking a heap snapshot in the near heap limit would
result in a full GC, then the overhead of the promotions would
cause another invocation of the heap limit callback and it can
raise the limit in the second call to avoid an OOM, so we test
that the callback can indeed raise the limit this way in this
case. When there is only one generation, however, there would
not be the overhead of promotions so the callback may not be
triggered again during the generation of the heap snapshot.
In that case we only need to check that the callback is called
and it can perform GC-triggering operations jsut fine there.
