refactor(component): refactor the implementation of Button and IconButton (#7716)

## Button
- Remove props withoutHoverStyle
   refactor hover impl with independent layer, so that hover-color won't affect the background even if is overridden outside
- Update `type` (renamed to `variant`):
  - remove `processing` and `warning`
  - rename `default` with `secondary`
- Remove `shape` props
- Remove `icon` and `iconPosition`, replaced with `prefix: ReactNode` and `suffix: ReactNode`
- Integrate tooltip for more convenient usage
- New Storybook document
- Focus style

## IconButton
- A Wrapper base on `<Button />`
- Override Button size and variant
  - size: `'12' | '14' | '16' | '20' | '24' | number`
     These presets size are referenced from the design system.
  - variant:  `'plain' | 'solid' | 'danger' | 'custom'`
- Inset icon via Button 's prefix

## Fix
- fix some button related issues
- close AF-1159, AF-1160, AF-1161, AF-1162, AF-1163, AF-1158, AF-1157

## Storybook
