[jeanregisser]

Summary

Part of #24875

Changelog

[General] [Added] - Add TurboModule spec for SourceCode

Test Plan

I'm not too sure how to update tests that are directly writing to NativeModules.

For instance:

react-native/Libraries/Image/__tests__/resolveAssetSource-test.js

Line 60 in 0815f81

NativeModules.SourceCode.scriptURL = 'http://10.0.0.1:8081/main.bundle';

or

react-native/jest/setup.js

Lines 261 to 263 in 0815f81

	SourceCode: {
	scriptURL: null,
	},

Let me know your thoughts on this.

Change them to getConstants() calls:

SourceCode: {
  getConstants: function() {
   return { 
     scriptURL: null, 
    }
  }
}

and

NativeSourceCode.getConstants().scriptURL = 'http://10.0.0.1:8081/main.bundle';
