[TextInputLayout] Add isActivated state for box stroke

Is your feature request related to a problem? Please describe.
Currently internally TextInputLayout doesn't use the ColorStateLists like other views do (but only ints) and therefore we can not set some states (isActivated, isChecked and custom ones) like we are able to do in other views.

Describe the solution you'd like
Please use ColorStateLists instead of Ints internally and add a support for isActivated state.

Describe alternatives you've considered
None. This view looks like it was created by a junior developer, who didn't have any idea how all views are being made in Android OS. Please assign a senior and do it a right way (not joking).

Additional context
None.

Inizia individuando TextInputLayout e il codice che gestisce i colori e lo stato del bordo del suo riquadro. Esamina come sono rappresentate attualmente le sue ColorStateLists, quindi verifica che activated e gli altri stati della vista influenzino il bordo in modo coerente con il comportamento esistente delle view Android; aggiungi o aggiorna test mirati se il progetto li fornisce.
