feat(trace): experimental traces for our tests (#3567)
This introduces basic tracing enabled in our tests.

What is captured:
- network resources;
- snapshots at the start of most actions;
- snapshot after the test failure.

How this integrates with test runner:
- context fixture calls private method context._initSnapshotter() and uses Tracer to trace all events;
- all tests share a single test-results/trace-storage directory to store blobs;
- each test has its own trace file.
- npm run show-trace opens a bare-minimum trace viewer that renders snapshots.

test: always setUnderTest in index.js, rename to setDevMode (#3662)
Root index.js is only used for local development, so
assuming dev mode there is fine. This way we do not have
to worry about calling setUnderTest early enough.
