Implementing visit_while_loop

[bhagyasreey]

Fixes #7

Summary of changes

1. _visit_while_loop Method

• Implements logic to simulate execution of a while loop during AST traversal.
• Supports break and continue control flow inside the loop body.
• Uses a counter (loop_counter) to prevent infinite loops via a max_iterations threshold.
• Evaluates the loop condition using Qasm3ExprEvaluator.evaluate_expression(...).

2. LoopControlSignal Handling

• Custom mechanism to simulate break and continue:
• These are raised by statement visitors like visit_break and visit_continue.

3. Loop Safety Mechanism

• Hardcoded max_iterations (e.g., 1024) to avoid infinite loops.
• Raises a custom exception like LoopLimitExceededError if the loop exceeds the limit.
