Rename _type modifiers to _state where applicable

[Sebastian Nitu]

Problem

There are a few components that use the _type_[value] modifier for displaying variants of info, success, caution and danger states. These should be more accurately renamed to _state_[value] modifiers which will better align with how they're used by the input component which already as a _type_[value] modifier. The input's _type_[value] modifier is used for setting an inputs type of form control (matching the attribute equivalent) styles.
