  [clang-tidy][NFC] optimize cache for config option (#121406)

Current implement will cache `OptionsSource` for each path, it will
create lots of copy of `OptionsSource` when project has deep nested
folder structure.
New implement use vector to store `OptionsSource` and only cache the
index. It can reduce memory usage and avoid meaningless copy.
