fix(select): update icon color and use correct focused class (#30342)

Issue number: 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. -->

There are a few items to note:
- Styles are using a non-existing focus class. It currently uses
`.has-focus` which isn't being used anywhere within `select.tsx`. It
seems that `.has-focus` comes a copy and paste that wasn't updated.
- Icon uses the highlight color when expanded, in item, and no fill.
This leads to the styling looking weird compared to when it's not in an
item especially since labels do not change colors. Only applies to `md`
mode.

- The focus without a validation status does not update the border
correctly when inside an item and has a solid fill. Only applies to `md`
mode.

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

- Styles are now using the correct focus class: `.has-focus`, removing
`ion-focused`.
- If the select is inside an item and has no fill then the icon will not
use the highlight color. Only applies to `md` mode.
