413e5808 - [clang-tidy][NFC] Don't store a redundant copy of `HeaderFileExtensions` in every check (#190302)

[clang-tidy][NFC] Don't store a redundant copy of `HeaderFileExtensions` in every check (#190302) #80333 removed local `HeaderFileExtensions` options; now there's just the global option, and its value lives in the `ClangTidyContext`. But every check still stores its own copy of it, a vestige of the old design which this change fixes.
