Update groovy TestFuzzer.java Enhance Fuzz Testing with Additional Custom Object Test Cases

[Shivam7-1]

PR Description: Added additional test cases for custom objects, including null handling, hash code consistency, toString validation, and large object array testing. Enhanced fuzz testing for equality, edge cases, and inheritance scenarios to improve robustness and reliability.

Key changes Done:

1. Null and Invalid Comparisons:

• testNullObjectEquality: Ensures that comparing a MyObject to null fails.
• Tests null array handling.

2. HashCode Consistency:

• testHashCodeConsistency: Ensures that two equal MyObject instances return the same hash code.

3. ToString Method:

• testCustomObjectToString: Verifies that toString() returns the correct string representation.

4. Large Object Array Handling:

• testLargeObjectArrayHandling: Tests large arrays of MyObject to see how the system handles them.

5. Inheritance Handling:

• testCustomObjectEqualityWithInheritance: A placeholder for future inheritance tests.
