JSX transform: add the debug source information

[kirillrogovoy]

Most other compilers, namely Typescript and Babel, support a "dev" mode when the compiled code would include the 5th argument of the react/jsx-dev-runtime function call which provides the data on the original source file.

return jsx(
  'div',
  {
    children: [
      jsx(
        'h1',
        { children: 'Hello, world!' },
        void 0,
        false,
+       { fileName: _jsxFileName, lineNumber: 14, columnNumber: 5 },
        this,
      ),
      'text text',
    ],
  },
  void 0,
  true,
+ { fileName: _jsxFileName, lineNumber: 13, columnNumber: 9 },
  this,
)

Some tools, such as impulse, leverage that data in dev runtime.

Once there's support for the new runtime API, it should be trivial to implement.

I'm ready to contribute, but I need help with higher-level design decisions.
