There's today a single boolean `debugEmulateFlutterTesterEnvironment` that determines certain behaviors in the engine to emulate how the Flutter Tester runs (more details at https://github.com/flutter/flutter/issues/145779). With this PR: - Run all engine unit tests in production mode by default. - Give tests more granular control over which test behaviors to enable/disable (e.g. Ahem font). - Keep it easy for framework tests to enable all emulation behaviors. Fixes https://github.com/flutter/flutter/issues/145779
