[i18n-input] Added component handling i18n translations for a single input

[obraud]

Description

• Added I18n panel component & model listing i18n translation
• Added first iteration of parent input component, displaying aforementionned panel on target element click. Usable in a form. ⚠️ This is not the final iteration for this component since it does not match LF needs for now

---

V1: The input in itself is a attribute component which prevents using it with other attribute component like luButton. It also implements ControlValueAccessor which will cause conflicts if used with other ControlValueAccessor component or directives.

V2: The input is a text form control. Panel has been simplified to be submit when clicking outside of it.
