Changelog: [internal]
We're modifying some core APIs in the RN render in following diffs, so this adds a simple benchmark as a safety mechanism to verify those don't regress performance significantly.

Pull Request resolved: https://github.com/facebook/react-native/pull/48882
Changelog: [internal]
The current hint for benchmarks is that the test body contains `unstable_benchmark` calls, but some benchmarks that need to use feature flags define their test bodies in a separate file, so the file containing the call to `unstable_benchmark` isn't the `-itest.js` one.
This adds a new hint to opt into optimized builds that uses the name of the test instead of its contents. If it contains `-benchmark` then we consider it a benchmark and do the opt in.

We're still iterating on this feature and making sure it reports stable results, so marking it as `unstable` to set expectations.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/48452
Changelog: [internal]
Implements a basic API to run benchmarks with Fantom (using `tinybench` under the hood):
```
import {benchmark} from 'react-native/fantom';
benchmark
.suite('Suite name', {
// options
})
.add(
'Test name',
() => {
// code to benchmark
},
{
beforeAll: () => {},
beforeEach: () => {},
afterEach: () => {},
afterAll: () => {},
},
)
.verify(results => {
// check results and throw an error if the expectations fail
});
```
Features:
* Print benchmark results in the console as a table.
* It opts into optimized builds automatically
* Verifies that optimized build is used (unless manually opting out of the check via `disableOptimizedBuildCheck`).
* Supports verification of results (making expectations and making the test fail if the benchmark doesn't meet some expectations).

Pull Request resolved: https://github.com/facebook/react-native/pull/48178
Changelog: [internal]
Adds a new mode for Fantom to run tests with dev-mode bytecode. Right now the modes were only dev (development with source code) or opt (optimized bytecode).

Migrating this type to an enum, which is safer, because it prevents errors like:
```
// when it's actually 'dev'
if (mode === 'development') {
}
```

Changelog: [internal]
Just a small cleanup to move `jest/integration/*` to `packages/react-native-fantom`, so everything related to Fantom (config, runner, runtime, etc.) is in the same directory.
