[SRU Justification]

[Impact]

To migrate the a version scheme that is well-known to all parties.

[Fix]

Update debian upstream version to 1:0~NN.ddddd-git<hash>. Also based on
the upstream release/core88 HEAD at the time.

[Test Case]

1. install kernel headers packages. This should include kernel headers for generic-6.8, oem-6.8, linux-azure, linux-lowlatency according to kernel-versions dkms map
2. install backport-iwlwifi-dkms from -proposed and trigger dkms builds

[Where problems could occur]

iwlwifi dkms provides backward compatibility, but new features may still
depend on new firmware, which may not be available unless SRU-ed back to
noble.

[Other Info]

For Jammy, we will have oem-6.8 and hwe-6.8 soon, but no further plan
for 6.10 kernels. Currently it has nothing depending on a new iwlwifi
dkms release, so it will be skipped from this SRU, leaving only Noble as
the target.

========== original bug report ==========

In the past we're tracking the upstream master branch and create new
builds upon the lastest HEAD available at the moment. This, however,
creates ambiguity for tracking backport-iwlwifi development & releases,
because the upstream puts more emphasis on the coreNN releases instead
of the development branch master when investigating support of new
hardware models.

Currently backport-iwlwifi-dkms/noble, versioned 11510-0ubuntu1, is
built from upstream revision 11520, which maps to upstream git commit
41e354fb5f32 that is a few commits behind the release/core84 HEAD commit
6d8764841123 (revision 11517). To migrate to release/core84 branches, it
follows we will have to rebase our work to release/core84 HEAD and to
fix debian version with an additional epoch. The proposed new version
nubmer is 1:84.<rev>-git<hash>-0ubuntu1.
