[clangd] Cache include fixes for diagnostics caused by the same unresolved name or incomplete type.

Summary:
Multiple diagnostics can be caused by the same unresolved name or incomplete type,
especially if the code is copy-pasted without #includes. The cache can avoid making
repetitive index requests, and thus reduce latency and allow more diagnostics to be
fixed (we limit the number of index requests for each parse).
