Summary:
In T85279528, we're trying to add a RCTURLRequestHandler to the NativeModule system, when the NativeModule system is in an invalid state. This causes a crash. Longer term, this crash will go away when we delete the legacy NativeModule system. However, in the short term:
1. The parent of this diff (i.e: D26741053) ensures that all RCTURLRequestHandlers are TurboModule-compatible. This makes the modules std::vector passed into ModuleRegistry::resigerModules empty.
2. This diff makes ModuleRegistry::registerModules() noop when the modules std::vector is empty.
In tandem, these two diffs should mitigate this crash, by making sure we don't execute the code that crashes.

Summary:
## Motivation
We got this crash T67304907, which shows a `EXC_BAD_ACCESS / KERN_INVALID_ADDRESS` when calling this line:
```
NativeModulePerfLogger::getInstance().asyncMethodCallBatchPreprocessStart();
```
There are no arguments in that call, so I figured the only error could be when we try to invoke `getInstance()` or `asyncMethodCallBatchPreprocessStart()`.
This diff:
1. Removes the `NativeModulePerfLogger::getInstance()` bit. Now NativeModulePerfLogger is used via regular static C functions. So, there's no way that simply invoking one of the logging functions crashes the application: there's no vtable lookup.
2. Inside each logging function, when perf-logging is disabled, the global perflogger should be `nullptr`. This diff makes it so that in that case, we won't execute any code in the control group of the perf-logging experiment.
## Changes
**How do we enable NativeModule perf-logging?**
- Previously:
- `NativeModulePerfLogger::setInstance(std::make_shared<FBReactNativeModulePerfLogger>(...))`
- `TurboModulePerfLogger::setInstance(std::make_shared<FBReactNativeModulePerfLogger>(...))`.
- Now:
- `BridgeNativeModulePerfLogger::enableLogging(std::make_unique<FBReactNativeModulePerfLogger>(...))`
- `TurboModulePerfLogger::enableLogging(std::make_unique<FBReactNativeModulePerfLogger>(...))`
**How do we do NativeModule perf-logging now?**
- Previously:
- `NativeModulePerfLogger::getInstance().command(...args)`
- `TurboModulePerfLogger::getInstance().command(...args)`.
- Now:
- `BridgeNativeModulePerfLogger::command(...args)`
- `TurboModulePerfLogger::command(...args)`.
The benefit of this approach is that each method in `BridgeNativeModulePerfLogger` is guarded with an if check. Example:
```
void moduleCreateConstructStart(const char *moduleName, int32_t id) {
NativeModulePerfLogger *logger = g_perfLogger.get();
if (logger != nullptr) {
logger->moduleCreateConstructStart(moduleName, id);
}
}
```
Therefore, we don't actually execute any code when perf-logging is disabled.

## Motivation
This rename will fix the following CircleCI build failures:

## Investigation
We have 4 podspec targets that map to the same header namespace (i.e: `header_dir`) `ReactCommon`:
- **New:** `React-perflogger`: Directory is `ReactCommon/preflogger`, and contains `NativeModulePerfLogger.{h,cpp}`.
- `React-runtimeexecutor`: Directory is `ReactCommon/runtimeexecutor`, and contains only `RuntimeExecutor.h`
- `React-callinvoker`: Directory is `ReactCommon/callinvoker`, and contains only `CallInvoker.h`
- `ReactCommon/turbomodule/core`: Directory is `ReactCommon/turbomodule`, and contains C++ files, as well has header files.
**The problem:**
We couldn't import headers from `React-perflogger` in `ReactCommon/turbomodule/core` files.
**The cause:**
I'm not entirely sure why, but I was able to discern the following two rules by playing around with the podspecs:
1. If your podspec target has a cpp file, it'll generate a framework when `USE_FRAMEWORKS=1`.
2. Two different frameworks cannot map to the same `module_name` or `header_dir`. (Why? No clue. But something breaks silently when this is the case).
So, this is what happened when I landed `React-perflogger` (D21443610):
1. The TurboModules code generates the `ReactCommon` framework that uses the `ReactCommon` header namespace.
2. `React-runtimeexecutor` and `React-callinvoker` also used the `ReactCommon` header namespace. However, neither generate a framework because of Rule 1.
3. When I comitted `React-perflogger`, I introduced a second framework that competed with the `ReactCommon` framework (i.e: TurboModules code) for the `ReactCommon` header namespace. Rule 2 violation.
## Thoughts on renaming
- `<perflogger/NativeModulePerfLogger.h>` is too generic, and the `perflogger` namepsace is used internally within FB.
- `<react/perflogger/NativeModulePerfLogger.h>` matches our fabric header format, but I'm pretty sure that slashes aren't allowed in `header_dir`: I tested this and it didn't work. IIRC, only alphanumeric and underscore are valid characters for `header_dir` or `module_name`. So, I opted to just use `reactperflogger`.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/28893
`JSIExecutor::callSerializableNativeHook` converts the arguments from `JSI::Value` to `folly::dynamic`. Then, `RCTNativeModule` converts the arguments from `folly::dynamic` to ObjC data structures in its `static invokeInner` function.
Therefore, I decided to start the sync markers inside `JSIExecutor::callSerializableNativeHook`, which required me to expose these two methode `ModuleRegistry::getModuleName` and `ModuleRegistry::getModuleSyncMethodName`. This shouldn't modify performance because we eagerly generate a NativeModule's methods when it's first required. So, at worst, this is doing a cache lookup.

Summary:
This diff instruments two markers:
- JSRequireBeginning: From the start of the JS require to when we start creating the platform NativeModule
- JSRequireEnding: From the end of platform NativeModule create to the end of the JS require
In order to accomplish this, I had modify `ModuleRegistry::ModuleRegistry()` to accept a `std::shared_ptr<NativeModulePerfLogger>`. I also had to implement the public method `ModuleRegistry::getNativeModulePerfLogger()` so that `JSINativeModules` could start logging the JS require beginning and ending.
