Changelog: [internal]
This adds a new environment variable to Fantom that allows debugging the JS code in tests.
Usage:
```
FANTOM_DEBUG_JS=1 yarn fantom <test>
```
**Does NOT work in OSS yet**. We need to include a third-party library to send HTTP and WebSocket requests and implement a wrapper on top of it.

Changelog: [internal]
This changes the logic to find an available port for Metro on Fantom to do this outside Metro. Before, we'd set `0` as the port for Metro to find an available port, but in a following change we'll need to know the port before calling into Metro. This allows that.

Pull Request resolved: https://github.com/facebook/react-native/pull/52777
Changelog: [internal]
This significantly speeds up test execution in Fantom (around 2x in OSS and 6x at Meta) by starting a Metro server before all tests runs and reusing it across all tests to build test bundles, instead of spinning up a new Metro instance every time we run each test.
The architecture change (also considering the previous change in buck prebuilds) looks like this:
{F1980689532}
This is how is impacts execution times (compared to the baseline):
* OSS
* Before: 62s {F1980564286}
* After: 30s (**2x faster**) {F1980564265}
