Add a manual test for inspecting types that have a special VM implementation.

runtime/bin/vmservice/observatory/tests/ui/inspector.dart

+library manual_inspector_test;

Do we need a copyright notice?

Perhaps we should add a file level comment saying what this file is for and
directing people to manual_inspector_test.txt.

Added and likewise for the retainingPath test.

You have two typos on this line: Guage -> Gauge.
