Improve performance of cloning AST nodes (#19067 )

This PR improves the performance of when we need to clone some AST
nodes. We have a few places where we clone `Candidate`, `Variant` and
CSS `AST` nodes.

Right now we use `structuredClone`, which works, but it is a generic
solution. However, we do know the exact structure of these AST nodes, so
we can write specialized clone functions that are much faster.

## Test plan

1. All the tests still pass with this change
2. The performance is better:

```
  cloneCandidate - src/candidate.bench.ts > Candidate cloning
    1.72x faster than cloneCandidate (spread)
    74.03x faster than structuredClone

  cloneAstNode() - src/ast.bench.ts > Cloning AST nodes
    1.15x faster than cloneAstNode (with spread)
    33.54x faster than structuredClone()
```

Ready for review, but should be merged after #19059
