Function is_func_ptr_field

internal/cbm/extract_defs.c:6182–6201

Extract typed struct/class fields for cross-file LSP resolution (C/C++/CUDA/Go/Java/Rust etc.) Creates "Field" label definitions with return_type set to the field's type text. These are later collected by DefsToLSPDefs to build FieldDefs pipe-separated strings. Check if a field_declaration has a function-pointer declarator chain.
