CE-2687: Add skipped state
Added skipped state and instead of InlineStepper calculating the state of progress and steps, it's now takes a list of step objects that has it's own state. Leaving it up to the consuming component to shape step state.
Follow ups:
- add a step component with color and icon
- add a custom default stepper, current is not accessible and could be more scalable.
