[sc-50634] Erumu: Refactor Various Input Modules to Use New Input.Builder Module

[robmagary]

This is motivated by the current need to add input types for email and password while limiting the text that can be passed to the type_ <input-type> attribute and avoiding repetitive copying of existing module functions like render, fill, etc.

• Adds Input.Builder module and revises TextInput, FileInput, and CheckboxInput to use the builder
• Does not add additional input types but sets the pattern to do so.
• Preserves the previous API for the three input types, minus the recently added renderWithType helper in favor of the withEmailValue and withPasswordValue. Those could have been named withPasswordType and withEmailType, but I chose to follow the syntax of the withValue helper. It could also be confusing because withPasswordType implied the type is Password instead of String.
