Remove kind field from StackHandler.

Remove kind field from StackHandler.

This makes the Isolate::Throw logic not depend on a prediction of
whether an exception is caught or uncaught. Such a prediction is
inherently undecidable because a finally block can decide between
consuming or re-throwing an exception depending on arbitray control
flow.

There still is a conservative prediction mechanism in place that
components like the debugger or tracing can use for reporting.

With this change we can get rid of the StackHandler::kind field, a
pre-requisite to do table-based lookups of exception handlers.
