    linuxkpi: Add `struct kmsg_dump_detail`
    
    This structure is used in a modified definition of `struct kmsg_dumper`
    field `dump` in Linux 6.12. Therefore this field has two definitions put
    behind the values of `LINUXKPI_VERSION`.
    
    The DRM generic code started to use it in Linux 6.12.
