Initial CSS Nesting implementation.

Implement CSS Nesting (level 1), with syntax from the current draft.
This is a rough first implementation enabled only at the “experimental”
level; we do not support:

• Conditional groups (@media, @supports, @container)
  within nested rules.
• CSSOM.
• Developer tools support.
• Correct error handling in all paths.

We pass some of the WPT nesting tests, but not all (since we do
not support @media, for one). This feature is generally undertested.

The syntax is still subject to change.
