feat(segment-view): adds support for new ion-segment-view component (#29969)

Issue number: resolves internal

---------

<!-- Please do not submit updates to dependencies unless it fixes an
issue. -->

<!-- Please try to limit your pull request to one type (bugfix, feature,
etc). Submit multiple pull requests if needed. -->

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

Segments can only be changed by clicking a segment button, or dragging
the indicator

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

The segment/segment buttons can now be linked to segment content within
a segment view component. This content is scrollable/swipeable. Changing
the content will update the segment/indicator and vice-versa.

## Does this introduce a breaking change?

- [ ] Yes
- [x] No

<!--
  If this introduces a breaking change:
1. Describe the impact and migration path for existing applications
below.
  2. Update the BREAKING.md file with the breaking change.
3. Add "BREAKING CHANGE: [...]" to the commit description when merging.
See
https://github.com/ionic-team/ionic-framework/blob/main/docs/CONTRIBUTING.md#footer
for more information.
-->


## Other information

<!-- Any other information that is important to this PR such as
screenshots of how the component looks before and after the change. -->

**Limitations:**
- Segment buttons **cannot** be disabled when connected ton
`ion-segment-content` instances
- The `ion-segment` **cannot** be without a value when linked with an
`ion-segment-view`. If no value is provided, the value will default to
the value of the first `ion-segment-content`
