Remove excessive hint update queries

* Filter out queries for outdated buffers just before hint tasks spawn:
  multicared edits might empit standalone events simultaneously
* Only spawn inlay update tasks for visible buffers with corresponding
  language
* Do not spawn tasks for local projects' buffers without LSP servers
