internal/impl: refactor validation a bit

Return the size of the field read from the validator, permitting us to
avoid an extra parse when skipping over groups.

Return an UnmarshalOutput from the validator, since it already combines
two of the validator outputs: bytes read and initialization status.

Remove initialization status from the ValidationStatus enum, since it's
covered by the UnmarshalOutput.
