This low-level API implements virtual address space reservations on the
supported platforms. An AddressSpaceReservation supports similar
functionality as the global page management APIs in the OS class but
operates inside a continuous region of previously reserved virtual
address space. A reservation is backed by regular mmap mappings on
Posix, by placeholder mappings on Windows, and by VMARs on Fuchsia.

We had IsJSHandlerOnTop and IsExternalHandlerOnTop, which were almost
opposites but not quite. We often did the same computation repeatedly
for determining which kind of a handler is at the top (if any).

This CL simplifies the logic, and only does the three-way logic once:
either there's an external handler, a JS handler, or neither.

It also removes dead code from Isolate::ReportPendingExceptions: we
already do an early return if there's a JS handler on top, so we don't
need to re-check.

With https://crrev.com/c/3272577 we introduced a `StackFrame` cache for
the inspector, which is keyed on the script ID, line and column number,
so the syntactic properties of the function. However, the name that we
report for functions is dynamic and can change (per closure) by
explicitly reconfiguring the "name" property via

```js
var f = function() { /* ... */ }
Object.defineProperty(f, "name", {value: "super duper function"});
```

for example, so we need to take that into account as well, and only use
the cached `StackFrame` instance if the dynamic names still match up.
Otherwise we just overwrite the cached entry with a new instance (the
assumption here is that "name" isn't reconfigured often).

Until now, histograms associated with isolate counters were created
at the time of isolate initialization. This is too early because it
happens before persistent memory is configured. Histograms created
before persistent memory is set up are retrieved periodically but
infrequently and are not "flushed" on process termination. As a result,
a lot of samples from V8 are lost.

This CL implements lazy creation of counter histograms, the first time
that they are used.

To trigger speculative inlining, a function needs to run a few times on
Liftoff-tier, and then tier-up to Turbofan. We make sure this happens
by enabling --wasm-dynamic-tiering with a small budget, and running
the critical functions until {%IsLiftoffFunction} is false.
We also add an additional test.

This also fuzzes values of --budget-for-feedback-vector-allocation.

The CL converts uses of v8::internal::Worklist to heap::base::Worklist
which does not require to know the number of tasks working with the
work list upfront. heap::base::Worklist is the common implementation
for V8's heap and cppgc and should be used/optimized going forward.

See crrev.com/c/3277878 for context.

We should only transform extenral to internal function references when
passing a function value to a function-typed global or table. For their
externref counterparts, we should preserve the reference unchanged.
