[Skeleton] 新增col 设置圆角、 背景颜色属性

这个功能解决了什么问题

希望可以新增 ColItem 圆角属性 ， 这个在一些场景还是挺常用的
const getColItemStyle = (obj: SkeletonRowColObj): Styles => {
const styleName = [
'width',
'height',
'marginRight',
'marginLeft',
'margin',
'size',
'background',
'backgroundColor',
];
const style: Styles = {};
styleName.forEach((name) => {
if (name in obj) {
const px = pxCompat(obj[name]);
if (name === 'size') {
[style.width, style.height] = [px, px];
} else {
style[name] = px;
}
}
});
return style;
};

你建议的方案是什么

SkeletonRowColObj 新增 borderRadio 属性

Start by locating the SkeletonRowColObj type and the getColItemStyle entry point shown in the issue. Trace how the listed style properties are converted and applied, then add support for the requested borderRadio property and verify that ColItem renders the resulting rounded styling.
