Tabs: Update subcomponents to accept full HTML element props

What?

Updates the subcomponents (TabList, Tab, and TabPanel) to accept all of the HTML element props relevant to their underlying DOM elements.

This PR also removes some artifacts of an old icon prop that was removed earlier in the component's development. There were still some references in the types and tests files that needed to be removed.

Why?

Previously the Tabs subcomponents explicitly accepted props like className and style, but not the general props for their respective DOM elements. This made it hard to pass basic props, and made it necessary to overuse the render prop to gain access to them (example)

How?

Each of the subcomponents now leverages WordPressComponentProps to include all of the relevant HTML element props.

Testing Instructions

1. Open the Tabs default story in Storybook.
2. Edit the default story by adding some div related HTML props to a TabList and TabPanel subcomponent (hidden, style, className for example, but experiment with any prop that's valid on a div.)
3. Confirm that the props you've added are correctly passed to the rendered div for the subcomponent you modified.
4. Edit the default story by adding some button related props to a Tab subcomponent. Specifically, test an onClick to confirm that it's applied and functions correctly.
5. Have a snack. You deserve it.

This is testing well! ✅

Since props are being removed (className and style), I wonder if it would be beneficial to add any tests? But since this is utilizing WordPressComponentProps, it may be unnecessary. I'll leave that up to your discretion! Otherwise, I believe this just needs a CHANGELOG, and then it'll be ready to go.

Thanks @brookewp! I think I'll hold off on tests now... I feel like I'd be writing tests for WordPressComponentProps more than for Tabs itself - but I'm happy to add them in a followup later if we decide it's warranted!
