rGe692f36a678d: linuxkpi: Add `struct kmsg_dump_detail`
Summary

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.

I believe we settled on "the new version should be the default" you get even if LINUXKPI_VERSION is not defined?
