    GH-47277: [C++] r-binary-packages nightly failures due to incompatibility 
with old compiler (#47299)
    
    ### Rationale for this change
    
    The `r-binary-packages` job (specifically [C++ Binary Linux OpenSSL 
1.0](https://github.com/ursacomputing/crossbow/actions/runs/16314662786/job/46077638701#logs)
 and 1.1) has been failing since 15th July with this error:
    
    ```
    /arrow/cpp/src/parquet/encryption/encryption.h:175:62: error: use of 
deleted function 'arrow::util::SecureString::SecureString()'
             : column_path_(std::move(path)), encrypted_(encrypted) {}
                                                                  ^
    In file included from /arrow/cpp/src/parquet/encryption/encryption.h:26,
                     from /arrow/cpp/src/parquet/properties.h:30,
                     from /arrow/cpp/src/parquet/arrow/path_internal.cc:109:
    ```
    
    ### What changes are included in this PR?
    
    Remove the unconditional `noexcept` from `SecureString`’s default 
constructor so its exception specification now matches `std::string`’s on all 
libstdc++ versions.
    
    ### Are these changes tested?
    
    No but I'll run the failing CI job
    
    ### Are there any user-facing changes?
    
    No
