feat: slot for button in ion-input

• I agree to follow the Code of Conduct.
• I have searched for existing issues that already include this feature request, without success.

Describe the Feature Request

With the new ion-input syntax, I am not able to create inputs with embedded buttons anymore. In version 6, I used slot="end" on ion-item to achieve that effect (still had to move the button with CSS when using a floating label, but it worked).

Describe the Use Case

A show/hide password button inside the input. Would also be a way to customize the button that appears when using [clearInput]="true".
Material Design 2 has a couple examples of uses to that feature here: https://m2.material.io/components/text-fields#anatomy (under "Icons").

Describe Preferred Solution

A button slot in ion-input would do it, just like the new label slot.
