KTextbox: Support a "clearable" prop to show a clear button

[AlexVelezLl]

Product

For now in Studio to achieve some specs for the Studio Usability Enhancements project.

Desired behavior

Add a "clear" button in the KTextbox component that only appears if there is non-empty text. When the user presses the clear button, the text should be deleted.

Vuetify currently supports this using a clearable prop on its VTextField, so we can replicate this prop name.

The Value Add

We give the user an option to easily delete all the text they have written.
