Summary: Currently, bridge delegate can provide extra modules during bridge start up path. For TurboModules, we don't need this mechanism (if we need eager init, it will be done in a different way). So, let's ignore modules marked as RCTTurboModule if they are supplied as "extra native modules".

Summary:
This may be controversial.
Right now, RelayPrefetcher is initialized [here](https://fburl.com/p01iunr1), after bridge is initialized. I want to create a FBRelayPrefetcherModule instance eagerly (diff 3 in stack), and then pass that into the bridge module registry. This way, native side gets to use RelayPrefetcher before bridge is init, and JS still accesses the same instance of FBRelayPrefetcherModule.
The only other option is drastically change bridge init, to allow passing in some eagerly initialized instances.

Summary:
Previously, asking for an instance of NativeModule from the native side gave `nil` if the lazy modules have not been loaded, which is not consistent with the access from JS. This at least attempts to force load the lazy modules when asked from native.
p.s. one asks for a module by doing `[bridge moduleForClass:[FooBar class]]`.

D12904277 was my sad, optimistic attempt to fix this crash.
As @[100006577537606:Slobodan] mentioned on T35879909, the real issue is that moduleRegistry is being created (using _moduleDataByID dict) concurrently while we try to append to this dict.
I added locks around these usage of _moduleDataByID.

[RN] Relax the requirement that lazy module cannot be initialized on the main thread
I tried to understand the D5364734 that intoduced this, and I am not sure, but belive that asserting here is too strict. If you have a module that you want to lazily initialize, and module does not demand the main queue, it should be just a warning if you run on the main queue, not necessarily an error.

Instead of asking existing modules to implement `+allowJSIBinding`, introduce a temporary "empty" protocol so modules can just adopt it for migration purpose.
Eventually this protocol may just go away.
Modules need to adopt both `RCTBridgeModule` and `RCTJSINativeModule` for time being for backward compatibility.
p.s. the entire system isn't enabled yet, this is just some of the pre-reqs for NativeModule improvements.

Summary:
To be able to test out new approach for NativeModules, introduce a simple runtime flag to enable the new system (doesn't exist yet). In addition, each module should declare a static `+ (BOOL)allowJSIBinding` in the objc class to be considered for the new approach. Doing so skips the processing of the module during bridge startup.
Note: this doesn't do anything special for `- (NSArray *)extraModulesForBridge:(RCTBridge *)bridge` impl yet.

Summary:
@public
The bridge may send the reload event twice when reloading JS in some rare condition. The 2nd one was actually when the "new" bridge wasn't valid yet, so log an error if that happens. This may happen if the connection to Metro server gets into a weird state. Restarting Metro would solve the problem.
The issue was that `RCTBridgeWillReloadNotification` fired twice for each reload with metro connected.

Summary:
Fixes: #18384
Previously line 42 had a warning of: `Field 'm_jsThread' will be initialized after field 'm_delegate'`
This appears to be because the private member fields are declared in a different order than the initializer-list was told to initialize things.
I chose to re-order the initializer list because that fixes the warning by matching the code structure to what the compiler was telling us it was going to do.
An alternate fix would be to change the order of the member variables declared in the `private:` section to match the coded order in the initializer list. This might be the right move if the initializer list had the correct intent, but this would be a breaking change from a behavior perspective, so I'd need somebody with more knowledge to suggest this is the right move.
A. Examine line to see the warning is gone.
B. Get a C++ guru to figure out the intent of this file and see if this actually exposed a bug that recommends we go with the alternate fix suggested above.
