[CORE] Implement if-else Contitional

[Icarus131]

The first step to accommodate conditional branching is to implement a simple if-else statement.

TODO:

• Extend the parser to handle basic if-else syntax
• Add support in expr.ml for conditional expressions and statements.
• Update codegen.ml to generate appropriate branching code for if-else constructs.
