aab50a3124 Rename ShortExternalString to UncachedExternalString. 
"short" external strings are not short, they mean that the external data
pointer is not cached. Rename the various classes and objects to align
with the actual meaning.

ce06603212 [debug] use flag to decide whether CallHandlerInfo has side effect 
Makes CallHandlerInfo its own instance type, with an additional
map to distinguish side-effect-free handlers. In a followup, we
can expose an API flag to set the map.

This CL does not support whitelisting calls to ObjectTemplates
that use SetCallAsFunctionHandler().
