Summary:
Fantom was disabling Metro hierarchical lookup in all cases when `JS_DIR` is set. The intention is that `node_modules` folders other than the configured `JS_DIR/public/node_modules` are not used.
However, this leads to incorrect resolution where a transitive dependency is not hoisted. If the origin of the resolution is already inside `node_modules`, we must perform a hierarchical lookup to avoid picking up just whichever version happens to be hoisted to `node_modules` root.

Pull Request resolved: https://github.com/facebook/react-native/pull/49251
Changelog: [internal]
Components like `AppContainer` require passing the rootTag as a prop, but we don't have access to it from Fantom unless we render something in the root and access it via the RootTagContext. This exposes the rootTag of the Root as a method so we can use it in initial render too.

Pull Request resolved: https://github.com/facebook/react-native/pull/49254
Changelog: [internal]
This is just a convenience method to do:
```
Fantom.dispatchNativeEvent(node, 'click');
```
Instead of:
```
runOnUIThread(() => {
enqueueNativeEvent(node, 'click');
});
runWorkLoop();
```
Which is too verbose and people rarely need this level of granularity in tests.
Note that, in Fabric, we have methods called `dispatchEvent` that don't match 1:1 with this API. In that case, `dispatchEvent` is more aligned with Fantom's `enqueueNativeEvent`.

Changelog: [internal]
Renaming this low level method as `enqueue` is more accurate in this case than `dispatch`, which is misleading because it actually doesn't dispatch it to JS.
We should also rename this in Fabric, but that's a larger and breaking change, so just making the change in Fantom for now. This is a trade-off between convenience/ergonomics of the testing API vs. alignment with the internal nomenclature. In this case we favor the first.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/49125
Changelog: [internal]
This adds support for taking JS memory heap snapshots from Fantom tests via `Fantom.saveJSMemoryHeapSnapshot`. This can be used in one-off tests to do memory analysis and determine the existence of leaks:
```
// Warm up
Fantom.saveJSMemoryHeapSnapshot('/path/to/my/1.heapsnapshot');
// Do work
Fantom.saveJSMemoryHeapSnapshot('/path/to/my/2.heapsnapshot');
// Clean up
Fantom.saveJSMemoryHeapSnapshot('/path/to/my/3.heapsnapshot');
```
Load these snapshots in Chrome and select "Objects allocated between 1 and 2" in the dropdown to see the potentially leaked objects.
In the future we could introduce additional utilities to analyze the snapshots and do the detection automatically, e.g.:
```
// Warm up
const baseline = Fantom.takeJSMemoryHeapSnapshot();
// Do work
const before = Fantom.takeJSMemoryHeapSnapshot();
// Clean up
const after = Fantom.takeJSMemoryHeapSnapshot();
const leaks = findMemoryLeaks(baseline, before, after);
expect(leaks.sizeKB()).toBeLessThan(THRESHOLD);
```

Changelog: [internal]
Native APIs so far have returned instance handles from React to reference nodes in the rendered UI tree, but now that we're adding support for the document API, this isn't sufficient to represent all types of nodes. Both for the document and for its `documentElement`, we don't have an instance handle from React that links to the node, but we're going to represent that differently.
This is a refactor so the existing methods use a mostly opaque `NativeNodeReference` type so we can implement it as a union of React instance handles and the future types we're going to introduce to support document.

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.

Modifies the execution of benchmarks in CI to run benchmarks in test mode when they don't define a `verify` method.
If a benchmark uses `verify`, the test is meant to make sure that the benchmark doesn't regress in CI. If it doesn't, then running the benchmark on CI doesn't provide much value. In that case, we run a single iteration of each test case just to make sure things don't break over time.

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).
