[Feature Request] Improve Typography copyable

[afc163]

Now we support a copy button with original text: https://codesandbox.io/s/interesting-river-vtoqf?file=/index.js

<Paragraph copyable={{ text: 'Hello, Ant Design!' }} />

There is three problems to resolve:

1. Cannot customize copy icon.
2. The copy icon has extra margin-left.
3. There is no good way to change default Copy and Copied in Tooltip.

The new API we are looking for should be:

<Paragraph
  copyable={{
    text: 'Hello, Ant Design!',
    onCopy: () => {},
+   icon: <Icon />,
+   tooltips: ['Copy', 'Copied'],
  }} 
/>

tooltips is no need. It's controlled by ConfigProvider locale. icon support customize is good enough.

It is a common need to customize tooltip for each copy button.
