[code-reflection] RFR: New Examples: Dialects and Dynamic Function Builds [v4]

[Juan Fumero]

> - `DialectSample`: Example of how to extends the code reflection `Op` to create a new dialect. 
> - `DynamicFunctionBuild`: Example of how to create a new function dynamically to compute the inverse of a square root.  The code model is built dynamically for a new method and it is evaluated in the `Interpreter`.
