feat(time-input): add clear method and enhance validation behavior fo…

[RamVinayMandal]

💡 What is the current behavior?

ix-time-input validation is not fully aligned when a value is removed after previous interaction.

• Optional time inputs are not consistently valid when cleared after being invalid.
• Required time inputs are not consistently shown as invalid when cleared or emptied.
• ix-time-input does not provide a public clear() method to clear the value and validation errors.
• novalidate and dynamic required handling are not fully aligned.

GitHub Issue Number: #

🆕 What is the new behavior?

• Add a public clear() method to ix-time-input to clear the value and validation errors.
• Optional invalid time inputs become valid when cleared.
• Required time inputs become required-invalid when emptied.
• Align validation behavior for clear/empty handling, novalidate, and dynamic required changes.
• Add missing component tests for these scenarios.

Code Review

This pull request adds a clear() method to the ix-time-input component and aligns its validation logic for required fields, novalidate forms, and dynamic attribute changes. Key feedback includes a suggestion to dynamically remove all validation classes during clear operations to ensure consistency, a request to justify or remove focus logic that might trigger unexpectedly during suppressed validation, and the removal of an unused utility function.
