94925d5eb7 TM iOS: Verify that module class conforms to RCTTurboModule before instantiating
Summary: At times, the lookup logic may find a class that's not compliant with RCTTurboModule. If so, it shouldn't be instantiated, and we assume the module doesn't exist.

aa39cb6d9f Remove assertion on TurboModule existence
Summary:
It's okay for TurboModules to not exist. Therefore, `__turboModuleProvider(moduleName)` should return null if `moduleName` doesn't refer to an actual TurboModule. The current implementation assumes that the TurboModule must exist, and therefore, it crashes the app when it doesn't (assertion error).

This change is important because it helps us land D13887962. When we switch `I18nResources` to `TurboModuleRegistry` in D13887962, on Wilde, it won't be found in `NativeModules`. Therefore, we'll try to lookup this module in `__turboModuleProvider`, and this will crash the app. It seems like `I18nResources` is a Java-only module?

0ceefb40d5 Enable module lookup in TurboModules
Summary:
NativeModules are instantiated by the bridge. If they choose, they can capture the bridge instance that instantiated them. From within the NativeModule, the bridge can then be used to lookup other NativeModules. TurboModules have no way to do such a lookup.

Both NativeModules and TurboModules need to be able to query for one another. Therefore, we have four cases:
1. NativeModule accesses NativeModule.
2. NativeModule accesses TurboModule.
3. TurboModule accesses NativeModule.
4. TurboModule accesses TurboModule.

In summary, this solution extends the bridge to support querying TurboModules. It also introduces a `RCTTurboModuleLookupDelegate` protocol, which, implemented by `RCTTurboModuleManager`, supports querying TurboModules:
```
protocol RCTTurboModuleLookupDelegate <NSObject>
- (id)moduleForName:(NSString *)moduleName;
- (id)moduleForName:(NSString *)moduleName warnOnLookupFailure:(BOOL)warnOnLookupFailure;
- (BOOL)moduleIsInitialized:(NSString *)moduleName
end
```

If TurboModules want to query other TurboModules, then they need to implement this protocol and synthesize `turboModuleLookupDelegate`:

```
protocol RCTTurboModuleWithLookupCapabilities
property (nonatomic, weak) id<RCTTurboModuleLookupDelegate> turboModuleLookupDelegate;
end
```

NativeModules will continue to use `RCTBridge` to access other NativeModules. Nothing needs to change.

When we attach the bridge to `RCTTurboModuleManager`, we also attach `RCTTurboModuleManager` to the bridge as a `RCTTurboModuleLookupDelegate`. This allows the bridge to query TurboModules, which enables our NativeModules to transparently (i.e: without any NativeModule code modification) query TurboModules.

In an ideal world, all modules would be TurboModules. Until then, we're going to require that TurboModules use the bridge to query for NativeModules or TurboModules.

`RCTTurboModuleManager` keeps a map of all TurboModules that we instantiated. We simply search in this map and return the TurboModule.

This setup allows us to switch NativeModules to TurboModules without compromising their ability to use the bridge to search for other NativeModules (and TurboModules). When we write new TurboModules, we can have them use `RCTTurboModuleLookupDelegate` to do access other TurboModules. Eventually, after we migrate all NativeModules to TurboModules, we can migrate all old callsites to use `RCTTurboModuleLookupDelegate`.

8a50bc3ab3 iOS: Make each module implement getTurboModuleWithJsInvoker: instead of having centralized provider
Summary:
For better modularity, each module conforming to RCTTurboModule should provide a getter for the specific TurboModule instance for itself. This is a bit more extra work for devs, but simplify tooling and allow better modularity vs having a central function that provides the correct instance based on name.

Note: Android may or may not follow this new pattern -- TBD.

e6f7d69428 Move Android TurboModules to github
Summary:
This commit moves all the turbo module files for Android to Github.

Note that gradle build is not yet enabled.
Sample Turbo Modules will be added in a later commit.

Other missing features

- Support for `CxxModule`
- Remove usage of folly::dynamic for arguments and result conversion
- Support for Promise return types.

f2fccbb327 Moved TurboModule iOS core to github
Summary:
This is the iOS binding for TurboModule.

To install the TurboModule binding:
* Provide `RCTCxxBridgeDelegate`
* Provide `RCTTurboModuleManagerDelegate`

Somewhere in `RCTCxxBridgeDelegate` impl:

```
RCTTurboModuleManager *manager = [[RCTTurboModuleManager alloc] initWithRuntime:&runtime bridge:bridge delegate:self];
[manager installJSBinding];
```

Doing so will install `global.__turboModuleProxy()` in JS space.

Note:
* The full instructions will be provided once all pieces are moved to OSS.
* Sample modules and binding setup will be provided later.
