LOG: [clang-tidy][NFC] Move `ClassifiedToken` to cpp file (#196820)

`ClassifiedToken` is used in only the implementation of
`UseTrailingReturnTypeCheck`. Move it into the unnamed namespace of the
cpp file instead of it being in the header.

Added: 
    

Modified: 
    clang-tools-extra/clang-tidy/modernize/UseTrailingReturnTypeCheck.cpp
    clang-tools-extra/clang-tidy/modernize/UseTrailingReturnTypeCheck.h
