IconButton style prop is not manageable due to container element.

### Current behaviour

When you add style prop such as zIndex to IconButton component it's no applied because IconButton wrapped in Surface component which has static styles defined.

### Expected behaviour

When adding zIndex property it applies to Surface component and works.
### How to reproduce?

### Preview

How it looks when I add zIndex: 1 to IconButton style prop
How it looks when I add View wrapper with zIndex: 1
### What have you tried so far?

### Your Environment

| software | version
| --------------------- | -------
| react-native | 0.73.4
| react-native-paper | 5.11.3

首先定位 IconButton 和 Surface 组件的实现，并使用指定的 React Native 和 react-native-paper 版本重现所报告的示例。跟踪 IconButton 的 style prop 如何传递到渲染出的容器；当该 prop 中的 zIndex 和 position 按预期影响组件，并为此行为添加回归检查时，该 issue 即完成。
