Motivation
We should be collecting and caching inlay hints as part our combined requests. That way, we only perform the work once per document state and if the user keeps scrolling the document, we just filter the ones to show based on the given range.
This prevents another AST traversal and improves our performance on user edits.
Implementation
The idea is to collect and cache inlay hints during the combined requests, but we still keep the request itself separate so that we can apply the range if user is scrolling up and down.
Automated Tests
Current tests should cover it.
