Reland: Add Scoped Context Info (Isolate) to V8 Traces

Reland: Add Scoped Context Info (Isolate) to V8 Traces

This patch adds the newly added support for contexts in V8 Tracing, as well
as use it to mark all the entry points for a V8 Isolate.

Update for reland: The current tracing interface needs to be updated (AddTraceEvent),
but the embedders need to migrate to the new version before removing the old version.
(Reland of: https://codereview.chromium.org/1686233002)

The revert happened because the 2 signatures of the old and new AddTraceEvent where different
so it threw an overload-virtual error on cross arm debug. This issue is temporary, and to solve
it, I added an implementation of the old and new everywhere until the embedder implements the new.

Hi Jochen,

I added some dummy bodies that I will remove once I update the chromium
implementation to be compatible with the arm cross compiler.
