Fix clang-format issue with 'new' and 'delete' keywords in C files

This patch resolves an issue in clang-format where 'new' and 'delete' were incorrectly recognized as keywords in C files. The fix modifies the TokenAnnotator::spaceRequiredBetween to correctly handle 'new' and 'delete' as an identifier in C code, preventing incorrect formatting.
