[Tabs] TabPane needs an additional property for tab displayed in overflow dropdown

[rinick]

• I have searched the issues of this repository and believe that this is not a duplicate.

What problem does this feature solve?

TabPane.tab is used both to display both the tab button and the tab in dropdown menu when there is overflow.
Same react element rendered in 2 different places sometimes can cause issues

• when tab has a special style that shouldn't be used in dropdown
• when tab has mouse event or drag drop handler
• when any element in tab need to use react ref

What does the proposed API look like?

export interface TabPaneProps {
  menuTab?: React.ReactNode;
}
