Changelog: [internal]
This adds a new getter for `document` in the `Root` class in Fantom tests to easily access the document instance for the root.
This isn't very useful at the moment, but will be very useful when we introduce `document.getElementById`, so we can access arbitrary nodes very easily.

We're shipping this soon and most tests already using DOM APIs to make assertions, so it's easier if we just "ship" in tests.

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.

Summary:
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`.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/49253
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);
```
