[testdriver] Detect testharness context lazily

Currently, loading testdriver.js before testharness.js causes testdriver.js to think it's in a non-testharness context even after testharness.js is loaded. To reduce surprises for test authors, defer evaluation of is_test_context to when actions actually need to be created or handled.
