1/n Add new JsErrorHandler buck target to parse JS errors in C++

Summary:
Changelog: [Internal][Added] 1/n Add new JsErrorHandler buck target to parse JS errors in C++

This JsErrorHandler.cpp class uses the same regex logic as [stack-trace-parser.js](https://github.com/errwischt/stacktrace-parser/blob/master/src/stack-trace-parser.js#L121) in order to parse JS errors into an array of stack frames.

In RN, stacktrace-parser is called from [Devtools/parseErrorStack.js](8bd3edec88/Libraries/Core/Devtools/parseErrorStack.js (L46)).
