Changelog: [internal]
This adds support for Fantom options in tests to configure different aspects of the test execution.
For now, it only supports specifying the mode (dev or opt) so we can try things without having to change the runner (watch mode still works if you change mode :D).
Fantom options are specified as pragmas in the docblock of the test. E.g.:
```
/**
* flow strict-local
* format
* fantom_mode opt
*/
```
We expect this is mostly going to be used for one-time tests and that regular tests won't specify the mode (they'll just run in dev mode).
Maybe we can evolve this in the future to specify that you want a test to be executed in both modes, to ensure the behavior is consistent in dev/prod.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/48015
Changelog: [internal]
Right now, when we run individual Fantom tests, we compile Hermes and the RN Tester CLI as part of the test, which causes the first test to run to be very slow and the remaining tests in the same run to be very fast.
This is misleading because it makes it look like the test itself is slow, when it's actually paying a price for everyone.
Fortunately, Jest has an option to do a global setup before any tests in the project run (and it doesn't run if none of the tests in the project run, in multi-project setups), so we can use it to do the necessary warmup so it doesn't end up being attributed to individual tests.

Just a small refactor in preparation for a following change that will add more usages for these utilities. It also cleans up the runner file which is good too.

This implements symbolication of error stack traces in Fantom tests. We just needed to ask Metro to generate source maps and use the `source-map` package to process the stack traces that we get back from the runtime.

Changelog: [internal]
This flag allows us to run optimized mode by using the right buck modes for the Fantom CLI, using minified + dev in Metro and building bytecode using Buck as well.
It's disabled by default but in the future we can enable it based on the configuration in the test file (e.g.: if it's a benchmark) or we can run tests in both modes by default to catch problems caused by the differences between environments.

This helps with debugging when adding logs in native code. By default they're logged to stderr and not shown in the Jest output, but we can opt into getting them with this new flag.

Changelog: [internal]
AppRegistry logs are showing up again in Fantom because we changed the order and now they're not necessarily showing up last.
This fixes that by filtering them out in any position.
