Move TurboModuleRegistry (JS) to github
Summary: Moved the JS wrapper function to github. To access a TurboModule from JS: ``` export interface Spec extends TurboModule { +func1: () => number, } const module = TurboModuleRegistry.get<Spec>('SampleTurboModule'); ``` This assumes: * the binding on the native side has been installed properly, i.e. `global.__turboModuleProxy` needs to be installed properly. * the module `SampleTurboModule` is registered properly in native. More instructions will be provided later. Reviewed By: yungsters Differential Revision: D13584561 fbshipit-source-id: 50d29d88787f8d9caa7a3ee0d54d378db866515c

/**

* NOTE: This is React Native specific export type.
|

*
|
||||
* RCTExport is an interface type that allows native code generation for React
|
||||
* Native native modules. It exists as a hint to the codegen tool that any
|
||||
* interface that extends it needs to be codegen'ed. Example usage:
|
||||
*
|
||||
* export interface RCTFoobar extends RCTExport<void> {}
|
||||
*
|
||||
* Native definition for RCTFoobar will then be generated.
|
||||
*
|
||||
* The type param T is a placeholder for future codegen hinting, like versioning
|
||||
* information, native base classes, etc. For now, simply use `void` type as
|
||||
* there's nothing to give hint about.
