Original commit message:
[wasm] Fix deadlock in async wrapper compilation
If compilation is cancelled while wrapper compilation is running, the
tasks spawned for the {AsyncCompileJSToWasmWrapperJob} will return
immediately, but {GetMaxConcurrency} will still return a positive
value. Hence {Join()} will spawn another task, resulting in a
livelock.
We could fix this by checking for cancellation in {GetMaxConcurrency},
but that requires taking the compilation state lock.
So this CL fixes the issue by dropping the number of outstanding
compilation units by to (basically) zero. We can't unconditionally drop
to zero because another thread might concurrently execute a wrapper
compilation and still call {CompleteUnit} afterwards. Hence only drop
outstanding units by the amount of not-yet-started units.

libstdc++: fix incomplete type in v8::internal::is_subtype<T, U>
Using std::convertible with incomplete types is UB. However, till
GCC 12 it was accepted and std::convertible returned false.
This fails now for e.g. v8::internal::WasmArray. Use
std::disjunction and std::conjunction instead which are short-
circuiting, because std::is_base_of<T, T> is already true.

Original commit message:
Add an `v8::ArrayBuffer::WasDetached` method to the C++ API
V8's C++ API does not give a way to tell whether an ArrayBuffer has
been detached from the `v8::ArrayBuffer` class. In fact, as far as can
be told from the C++ API without running JS code, detached
ArrayBuffers behave the same as zero-sized ArrayBuffers and there is
no way to observe the difference. However, this difference can be
observed in JS because constructing a TypedArray from a detached
ArrayBuffer will throw.
This change adds a `WasDetached` method to the `v8::ArrayBuffer` class
to give embedders access to this information without having to run JS
code.

[runtime] Clear array join stack when throwing uncatchable

Array#join depends array_join_stack to avoid infinite loop
and ensures symmetric pushes/pops through catch blocks to
correctly maintain the elements in the join stack.
However, the stack does not pop the elements and leaves in
an invalid state when throwing the uncatchable termination
exception. And the invalid join stack state will affect
subsequent Array#join calls. Because all the terminate
exception will be handled by Isolate::UnwindAndFindHandler,
we could clear the array join stack when unwinding the terminate
exception.

Original commit message:
Add option to report discarded allocations in sampling heap profiler
A couple of customers have asked about using devtools to get information
about temporary allocations, with the goal of reducing GC time and/or
peak memory usage. Currently, the sampling heap profiler reports only
objects which are still alive at the end of the profiling session. In
this change, I propose adding configuration options when starting the
sampling heap profiler so that it can optionally include information
about objects which were discarded by the GC before the end of the
profiling session. A user could run the sampling heap profiler in
several different modes depending on their goals:
1. To find memory leaks or determine which functions contribute most to
steady-state memory consumption, the current default mode is best.
2. To find functions which cause large temporary memory spikes or large
GC pauses, the user can request data about both live objects and
those collected by major GC.
3. To tune for minimal GC activity in latency-sensitive applications
like real-time audio processing, the user can request data about
every allocation, including objects collected by major or minor GC.
4. I'm not sure why anybody would want data about objects collected by
minor GC and not objects collected by major GC, but it's also a valid
flags combination.
