Support objects for style attribute

[natemoo-re]

Changes

• Follow-up to MDX support #3706
• Adds support for style={{ color: 'red' }} props
• Importantly, does not handle number => px string conversion for you. The logic in React that handles this is massive, and it's a convenience more than anything. Preact gets away with requiring explicit units.

Testing

Covered by #4002

Our JSX definitions should get updated so users don't get errors when using objects inside the editor

Here's the corresponding lines: for HTML elements and for SVG elements
