Summary:
The hermes profiler doesn't work currently, I tracked down the problem to a couple of things.
- Need to call `registerForProfiling` to enable profiling for a specific runtime. I added the call at the same place where we enable the debugger.
- `runInExecutor` didn't work and call its callback. Not sure exactly why, but using `executor_->add` like we do in a lot of other places to run code on the executor works.
- `GetHeapUsageRequest` seems to cause some deadlocks. JS contexts were not detected reliably, I suspect this is related to deadlocks when trying to run on inspector executor. `GetHeapUsageRequest` doesn't actually need any data from the inspector so there is no need to run it on that queue. To fix it I moved the call to use `runInExecutor` instead.

[General] [Fixed] - Fix hermes profiler

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.

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.

Summary:
Changelog: [Internal]
Provide a `HermesRuntime` from the `RuntimeAdapter` (instead of a decorated Hermes runtime).
As the Inspector can now directly access the `HermesRuntime` (which exposes access to the debugger), `RuntimeAdapter::getDebugger` is no longer necessary; remove it.

Changelog: [Internal]
Make runtime use more consistent, always using the same undecorated runtime. This prevents the previous mixing of decorated and undecorated runtimes.

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.

Summary:
Microsoft’s RN for macOS fork supports the Hermes engine nowadays https://github.com/microsoft/react-native-macos/pull/473. As a longer term work item, we’ve started moving bits that are not invasive for iOS but _are_ a maintenance burden on us—mostly when merging—upstream. Seeing as this one is a recent addition, it seemed like a good candidate to start with.
As to the actual changes, these include:
* Sharing Android’s Hermes executor with the objc side of the codebase.
* Adding a CocoaPods subspec to build the Hermes inspector source and its dependencies (`Folly/Futures`, `libevent`).
* Adding the bits to the Xcode build phase script that creates the JS bundle for release builds to compile Hermes bytecode and source-maps…
* …coincidentally it turns out that the Xcode build phase script did _not_ by default output source-maps for iOS, which is now fixed too.
All of the Hermes bits are automatically enabled, on macOS, when providing the `hermes-engine-darwin` [npm package](https://www.npmjs.com/package/hermes-engine-darwin) and enabling the Hermes pods.
## Changelog
[General] [Added] - Upstream RN macOS Hermes integration bits
Pull Request resolved: https://github.com/facebook/react-native/pull/29748
Test Plan:
Building RNTester for iOS and Android still works as before.
To test the actual changes themselves, you’ll have to use the macOS target in RNTester in the macOS fork, or create a new application from `master`:
