Expand and prettify README.md (#11158)

Reuses flutter.io homepage content to give README.md an upgrade, since this file will be the shop window of Flutter to a large part of newcomers. 

The downside is that we now have duplicate content that should be updated in unison with the main site but which cannot be easily copy-pasted, due to constraints of github's Markdown renderer.
