Make Isolate::GetIncumbentContext() work fine with ASAN

When ASAN is enabled, the previous implementation of
Isolate::GetIncumbentContext didn't work well due to mixture of fake
and real stack frames.

This patch converts an address in the fake stack frame to an address
in the real stack frame so that we can compare two addresses.

Make Isolate::GetIncumbentContext() work well with MSan

https://crrev.com/c/1343709 fixed GetIncumbentContext to work
with ASan, however, GetIncumbentContext didn't work well with
MSan because MSan uses a simulator which supports yet another
separate stack frame.

This patch fixes GetIncumbentContext so that it works well
with not only ASan but also MSan simply following the same way
as v8::TryCatch does.

i::GetCurrentStackPosition() solves the issue of ASan and
SafeStack (native but separate stack frame), and
i::SimulatorStack solves the issue of MSan (simulator stack
frame).
