test_runner.js: Reuse web workers (and devices) between CTS tests

This is necessary to run more than a few tests on the worker test steps;
otherwise they quickly run up against limits on the number of GPUDevices
that can be alive at once (which is due to some separate leak / slow GC
issue, which is harder to fix).

This was also the cause of all of the OOMs when I accidentally started
running all tests on workers: https://crbug.com/330573129#comment9
