97e6ea1371 Fabric: working podspecs & works in RNTester (#23803)
Summary:
This is the couple of hacks I used after I finished #23802 in order to get fabric working on RNTester. This is inspired from prior work by kmagiera.

The goal of this PR is to show others what I’m struggling with, and to eventually merge it sans hacks.

- Yarn Install
- Uncomment the commented out pods in RNTester's pod file
- Open RNTesterPods workspace
- Run App

- this is only for pods, the non-pod RNTester will no longer work until updated with fabric too.
- `SurfaceHostingView` & `SurfaceHostingProxyRootView` both try to start the surface immediately, this leads to a race condition due to the javascript not having loaded yet, the hack here is:
   1. Swizzle the `start` method on `RCTFabricSurface` to no-op when called.
   2. Add observer for `RCTJavaScriptDidLoadNotification`
   3. Call private method `_startAllSurfaces` on `_surfacePresenter` in AppDelegate when we receive `RCTJavaScriptDidLoadNotification`.

[General] [Added] - Use Fabric in RNTester

0d7faf6f73 Introduce prepareJavaScript jsi API
Summary:
This adds a new jsi API prepareJavaScript. This accepts the same
parameters as evaluateJavaScript() but does not evaluate anything; instead
it returns a new object PreparedJavaScript which can itself be evaluated,
via the new API evaluatePreparedJavaScript().

There is a new empty class PreparedJavaScript which may be subclassed by
each Runtime variant to store its particular prepared form.

7a8957c0be evaluateJavaScript to accept a shared_ptr instead of unique_ptr
Summary:
This changes jsi::evaluateJavaScript() to accept a
const shared_ptr<Buffer> & instead of a unique_ptr<Buffer.

It is reasonable to want to pass the same buffer to evaluateJavaScript()
multiple times. This will also help unify the API with the upcoming
prepareJavaScript() API.

Because shared_ptr has a unique_ptr constructor, this is compatible with
all call sites.

bdb084e8a8 Check for thread consistency in JSCRuntime
Summary:
In the version of JSC on iOS 11, creating a JSContext on one
thread and using it on another can trigger subtle and nearly
impossible to debug reentrancy-related crashes in the VM (see
https://bugs.webkit.org/show_bug.cgi?id=186827).  In !NDEBUG builds,
check for this case and throw an exception, so it can be detected
early.

bf2500e38e Switch to synchronous strategy for unprotect
Summary:
Older versions of JSC (ios 11 and before) have a bug which I
believe the ProtectionQueue mechanism tickles:
https://bugs.webkit.org/show_bug.cgi?id=186827

This removes the ProtectionQueue and replaces it with an atomic flag
to avoid calling unprotect after VM shutdown.

This also fixes a race condition in shutdown.
