Marshall Greenblatt 90aea56de6 ceftests: Change CreateTestRequestContext to async usage
With Chrome runtime, custom request contexts may be initialized asynchronously.
Wait for that initialization before using the request context.

This also removes TEST_RC_MODE_CUSTOM (uses TEST_RC_MODE_CUSTOM_WITH_HANDLER
instead) since we always need a handler to get the initialization callback.
