Add ways to configure EasingFunction::Steps via new StepConfig (#17752)
# Objective

- In #17743, attention was raised to the fact that we supported an
unusual kind of step easing function. The author of the fix kindly
provided some links to standards used in CSS. It would be desirable to
support generally agreed upon standards so this PR here tries to
implement an extra configuration option of the step easing function
- Resolve #17744

## Solution

- Introduce `StepConfig`
- `StepConfig` can configure both the number of steps and the jumping
behavior of the function
- `StepConfig` replaces the raw `usize` parameter of the
`EasingFunction::Steps(usize)` construct.
- `StepConfig`s default jumping behavior is `end`, so in that way it
follows #17743

## Testing

- I added a new test per `JumpAt` jumping behavior. These tests
replicate the visuals that can be found at
https://developer.mozilla.org/en-US/docs/Web/CSS/easing-function/steps#description

## Migration Guide

- `EasingFunction::Steps` now uses a `StepConfig` instead of a raw
`usize`. You can replicate the previous behavior by replaceing
`EasingFunction::Steps(10)` with
`EasingFunction::Steps(StepConfig::new(10))`.
