Simon Zünd db24e2000a [stack-trace] Separate stack-trace symbolization and serialization
This CL moves the code responsible for serializing a stack trace frame into
a string, out of messages.cc and into stack-frame-info.cc. Instead of
symbolizing the stack trace frame while serializing, the code is changed to
work on top of StackTraceFrame and StackFrameInfo objects.

The result is that the serialization code no longer cares when a stack trace
frame is symbolized. Symbolization could happen eagerly during capturing, or
lazily the first time any of StackFrameInfo fields are accessed.

Drive-by: Existing users of StackFrameBase::ToString are adapted to the
new SerializeStackTraceFrame API. This includes Isolate::PrintCurrentStackTrace,
which is changed to re-use the existing capturing and serializing mechanism.
