[Text-view] iOS native component does not provide leading- & trailing-icons

[JeremiasUX]

We received a request from the iOS-Spark developers:

• Do we need to provide leading- and trailing-icons for the text-view component in iOS?
• Slack thread: https://adevinta.slack.com/archives/C04LNCEMMUN/p1713866329435419

Issue:

• Native iOS component does not provide the leading- and trailing-icons out of the box
• Android, Web and Figma provides the leading- and trailing-icon
• Features would not be aligned across the platforms -> this could lead to confusions and questions

Goal of this ticket:

• [x] Investigate if there are use cases in production
• [x] Investigate how much work it would be to implement an iOS solution with icon
• [x] Find a solution that won't break after the first use cases
