deps: switch to upstream v8_inspector

This change picks up v8_inspector directly from the upstream chromium
repository [1]; dropping the intermediate repository. The upstream
code has been refactored substantially to make it easy to share code
without adaptation with Node.js.

The deps/v8_inspector directory is now simply a gathering of
dependencies:

* platform/v8_inspector: vendored from [2].
* platform/inspector_protocol: vendored from [3].
* deps/jinja2: vendored from [4].
* deps/markupsafe: vendored from [5].
