Summary:
Currently React Native codebase treats JS stack traces as array of dictionaries.
This diff switches the Red Box to use new `RCTJSStackFrame` for internal data representation, while keeping the exposed API unchanged. The next step would be to replace the rest of manual parsing and usage of dictionaries.
The new class has ability to parse the stack from raw strings or dictionaries.
