feat(search): Resolve deprecated attribute keys

[nsdeschenes]

Summary

• Add a cached utility that resolves deprecated and typed-tag attribute keys to their canonical search metadata name.
• Preserve the requested key when no search metadata exists.
• Resolve trace additional attributes through the utility before querying.

Example

getAttributeSearchMetadataKey('http.method');
// 'http.request.method'
