[Kannndev]

Closes #104

Hi @Kannndev,

Sorry for late response, I have updated few things in PR

• SVG as a fallback instead of unicode charactor
• Converted <span/> to <button/> element
• added aria-label w/ new key in i18n string since using unicode char or svg may cause problems for screen readers
• ClearIcon prop also accepts simple string as well as a param by default

Thanks @harshzalavadiya
