afohrman 0c49c64a57 Turn hint/label to error color when error is set.
Adds functionality to turn the floating label, or "hint", to the error color when the error is set. The error color for the label will match whatever the error color is set to via app:errorTextAppearance. In the case where no custom errorTextAppearance is set, the label gets set to the error color's default color, which is red/dark pink, depending on whether the text field is used in a dark or light theme.
