[NFC][CLANG] Fix static analyzer bugs about large copy by values (#75060)

Reported by Static Analyzer tool:

In getSourceRangeToTokenEnd(clang::Decl const *, clang::SourceManager
const &, clang::LangOptions): A very large function call parameter
exceeding the high threshold is passed by value

pass_by_value: Passing parameter LangOpts of type clang::LangOptions
(size 1784 bytes) by value, which exceeds the high threshold of 512
bytes
