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.

Previously the inspector was trying to handle step-out for async
functions by annotating the async stacks, but this was merely a
hack and didn't work reliably
(a) when the async caller that is `await`ing the result of the
callee was still in the synchronous part (because then there
was no async task yet in the inspector), or
(b) not at all when the async stack tracking wasn't enabled or the
maximum async stack depth was too small.
This CL replaces that hack with a pragmatic solution inside the
V8 debugger, where upon `await` we memorize the async function
object of the caller on the outer promise of the callee, and when
stepping out of the callee we check whether the returned promise
has a memorized async function object and if so, we schedule that
to resume.
This CL thereby effectively reverts https://crrev.com/c/1054618
and replaces it with a V8 debug solution, and thereby further
reduces the (memory) overhead of an AsyncStackTrace.

Compared to the previous CL this one is adding a TSAN suppression
for GlobalSafepoint::EnterSafepointScope. local_heaps_mutex_ of client
isolates may be locked in any order. This would be detected by TSAN as a
potential race. Add some additional DCHECKs to compensate for that
missing test coverage.
As a cleanup this CL also removes the unused methods ContainsLocalHeap()
and ContainsAnyLocalHeap() from LocalHeap.
