camc314 058a62f8a3 fix(semantic): track ambient contexts in SemanticBuilder (#24327 )

## Summary

- track TypeScript ambient contexts using a nesting depth in `SemanticBuilder`
- enter ambient context for declaration files and `declare` declarations, including declarations without their own scope
- replace namespace-based and ancestry-based ambient detection
- use the ambient context for reserved keywords, global augmentations, class heritage, computed class members, and bodyless accessors
- extend conformance coverage for ambient variables, properties, functions, and classes

This approach was discussed with overlookmotel yesterday after some brainstorming!
