Icon in IconButton not centered and cannot be centered

### Current behaviour
Icon in IconButton is not centered

### Expected behaviour
Icon to be centered

### How to reproduce?
Add background color to IconButton using the style prop.

### Preview

### What have you tried so far?
Adding `alignItems: 'center'` and `justifyContent: 'center'` to both `style` and `contentStyle`. `style` aligned the trash can icon a little bit horizontally, but it was still off.

Adding `backgroundColor` to both `style` and `contentStyle`.

### Your Environment

| software | version
| --------------------- | -------
| ios | x
| android | 13
| react-native | 0.82.1
| react-native-paper | 5.14.5
| node | 22.11.0
| npm or yarn | x.x.x
| expo sdk | x.x.x

Start by reproducing the IconButton layout on Android with a backgroundColor supplied through style, using the versions listed in the issue. Trace the IconButton implementation and its icon container to identify why the icon bounds are offset; done means the icon is centered when the button has a styled background.
