Instrument sync and async method calls (#28893)

Browse Source 
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.
