TextInput/TextinputGroup - consistent status/validation prop naming

Describe the enhancement or change
Related to convo chain at https://github.com/patternfly/patternfly-react/pull/10815#discussion_r1697713753

Would also pertain to other components that have a status/validation type prop. We should align on:

• whether the prop should be status or validation (personally would lean towards status)

• whether the prop type should only include valid class values, e.g. success, error/danger (another thing to align on), warning, info, and custom, or whether there should also be a "default" value to sort of unset it. If the latter, then does "default" make sense or should it be "none" or something else?

Is this request originating from a Red Hat product team? If so, which ones and is there any sort of deadline for this enhancement?

Any other information?
