Pieter De Baets f44469076d Remove unused Hermes inspector auto-attach logic
Summary:
We already support attaching-on-reload when a debugger was a previously connected, and this connection logic seems to slow down app startup by 2 seconds in debug mode when running on device.

Matt Blagden 6fcfe2e1b3 Identify debug sessions with a token
Summary:
The `RuntimeAdapter` may be used after `disableDebugging` has been called. To ensure the `RuntimeAdapter` is alive long enough for this use, the Inspector should continue to control `RuntimeAdapter`'s lifetime (which is currently done via a `unique_ptr` that's moved into the Inspector).

Callers need a way to identify the `RuntimeAdapter` after it has been moved into the Inspector so that debugging can be disabled via `disableDebugging`.

This could be done by switching from a `unique_ptr` to a `shared_ptr` (so the caller can keep a copy), but consumers don't really have a reason to hang onto the `RuntimeAdapter` instance. Instead, leave the `RuntimeAdapter` inside a `unique_ptr`, and have consumers use a token to identify instances.

Update all consumers of this API to use this new token interface.

Andreas Eulitz 60e7eb4d53 Fix reload hang after debugger break and continue (#34342)
Summary:
When using Hermes and direct debugging, creating a new React instance within the same process hangs when the previous instance was broken into and continued with a debugger (see test Test Plan section below for repro steps). This problem is tracked by issue [9662](https://github.com/microsoft/react-native-windows/issues/9662) in the react-native-windows repo.

In coarse strokes, the following code actions lead to the problem:
1. During the creation of the first React instance, the [lambda in ConnectionDemux::addPage](https://github.com/facebook/react-native/blob/main/ReactCommon/hermes/inspector/chrome/ConnectionDemux.cpp#L121) creates a LocalConnection object that adds a page title into the [inspectedContexts_](https://github.com/facebook/react-native/blob/main/ReactCommon/hermes/inspector/chrome/ConnectionDemux.h#L52) set (a singleton within the process).
2. React instance teardown does not clean up the inspectedContexts_ set.
3. Upon creating the second React instance, ConnectionDemux::enableDebugging sets [waitForDebugger](https://github.com/facebook/react-native/blob/main/ReactCommon/hermes/inspector/chrome/ConnectionDemux.cpp#L89) to true because it still finds the same title in the inspectedContexts_ set.
4. waitForDebugger being true results in the creation of a [PausedWaitEnable FSM state](https://github.com/facebook/react-native/blob/main/ReactCommon/hermes/inspector/InspectorState.h#L256) that hangs the Hermes VM [here](https://github.com/facebook/react-native/blob/main/ReactCommon/hermes/inspector/InspectorState.cpp#L118).

The change proposed here causes the inspectedContexts_ set to get cleaned up on instance teardown, thus resulting in the creation of the proper FSM starting state for the second React instance in the process.

[General] [Fixed] - Fix reload hang after debugger break and continue

Pull Request resolved: https://github.com/facebook/react-native/pull/34342

Test Plan:
### Repro Steps

The following repro steps involve the [Playground](https://github.com/microsoft/react-native-windows/tree/main/packages/playground) app from the react-native-windows repo. This is only illustrative; the same problem should occur with any RN host.

1. Start Metro bundler in [packages/playground](https://github.com/microsoft/react-native-windows/tree/main/packages/playground) folder.
4. Start Playground app. Adjust settings to use Hermes and direct debugging.
6. Select a package from the package dropdown and press the "Load" button.
7. Start Chrome and navigate to chrome://inspect. Wait a few seconds if necessary, then select "Hermes React Native" from the list of debug targets.
8. In the Chrome Inspector window, break script execution via the "Break" button.
9. Resume script execution via the "Play" button.
10. In the Playground app, select the same or another package, then press the "Load" button.

Result: Playground app hangs while displaying "Loading bundle" banner. Note that script execution cannot be resumed via the Chrome Inspector as step 6. above has already switched the debugger frontend into a "running" state.

With the change proposed here, step 7. does not hang (package reloads and executes). I've added an automated test for this scenario in the react-native-windows scenario (https://github.com/aeulitz/react-native-windows/blob/DebugHang2/packages/debug-test/DebuggingFeatures.test.ts#L245))

Matt Blagden d19cee3492 Use RuntimeAdapter to disable debugging
Summary:
Make the interface to enable/disable debugging symmetrical; both enabling and disabling are done by passing in a reference to the RuntimeAdapter.

Doing so requires moving ownership of the RuntimeAdapter, so each caller (java2js, arfx engine, React Native, react-native-github, and venice) has been updated to own their adapter.

Additionally, the two implementations of the Inspector connection (react-native-github and arfx engine) have been updated to expect and use the new argument.

`Connection::getRuntime` could be removed and replaced with calls to `Connection::getRuntimeAdapter::getRuntime`. I've left that choice to a followup diff, as this one is getting messy enough as it is.

Matt Blagden 3afe4c64f3 Use HermesRuntime to disable debugging
Summary:
Changelog: [Internal]

Debugging is enabled via `enableDebugging` with a `RuntimeAdapter` that provides a `HermesRuntime`. This same `HermesRuntime` should be passed to `disableDebugging`, not a decorated version. Change the argument type of `disableDebugging` to steer callers in the right direction.

John Porto c81a3c5242 Pass the correct runtime when disabling the debugger
Summary:
The RN Hermes Inspector keeps a mapping of pageId to
Connection. This mapping is created in the call to
enableDebugging. Later, when disableDebugging is invoked,
the inspector will iterate over the pageId to Connection map
to find which page to is being disabled.

The DecoratedRuntime enables debugging on construction, and
disables on destruction. When disabling debugging, the
DecoratedRuntime then passes the "naked" hermesRuntime,
which in turn gets checked against all connections' runtimes.

It turns our that ```HermesExecutorRuntimeAdapter::getRuntime```
returns the runtime **wrapped** by the DecoratedRuntime, and
not hermesRuntime itself.

This means that no connections match the request for
disabling debugging. Which means the Connection never
gets deleted, which in turns keep its underlying adapter (in
this case, the ```HermesRuntimeExecutorAdapter```) alive,
which has a shared_ptr to the runtime wrapped by the DecoratedRuntime.

Other than effectively leaking this connection (and thus the runtime),
this also causes an issue when the app tries to re-load the page -- at
which point the inspector will remove the old entry from the page to
connection mapping, thus initiating the destruction of the (leaked)
Runtime in a thread other than the thread that created the runtime.
