[TextInputLayout] Set hint style for both floated and default positions

Nadie ha tomado este issue todavía.

**Is your feature request related to a problem? Please describe.**
I'm adding text field programmatically and then setting styles to hint with `setHintTextAppearance`, but styles are working only on floated state and I couldn't find the way to apply them to hint at normal state. While `setDefaultHintTextColor`, does work for both. Setting textSize to editText child of TextInputLayout doesn't help also.

**Describe the solution you'd like**
I would like to `setHintTextAppearance` work for both state of hint.

**Describe alternatives you've considered**
It's probably also okay, if there will be new method for this? I don't see any other solutions.

**Additional context**
I would like to help, but I'm not so experienced, so I will need a little bit guidance.

Comienza localizando la implementación de TextInputLayout y el código que gestiona setHintTextAppearance para los estados de hint flotante y predeterminado. Traza cómo setDefaultHintTextColor se aplica a ambos estados, luego añade un comportamiento equivalente y verifica con las pruebas de Android correspondientes que el estilo del hint sea coherente en cada posición.
