Update inputs border-width

[Elton Garbin]

When the following components are in the focus state or hover state the border-width must be $border-width-thin, otherwise it should be border-width-hairline:

• Select
• Input
• TextArea

@julianasouza-s which border-width is in an active state?

Currently we change border color for this states:

  &:hover,
  &:focus,
  &:active {
    border-color: $color-brand-primary-down;
  }

I'd like to take advantage of this set and include a border-width: $border-width-thin.
