[SRU][J][K][PATCH] UBUNTU: [Packaging] sameport -- add support for sameport versioning

[Dimitri John Ledkov]

From: Andy Whitcroft <apw at canonical.com>

BugLink: https://bugs.launchpad.net/bugs/1993563

We currently support two types of kernels which are programatically
configured (marked "backports" in kernel-series and having
copy/local-mangle support):

  backports: those who express in an older series (~20.04.N)
  forwardports: those who express in a newer series (+22.04.N)

Add a new third type which represents "backports" into the same series:

  sameports: those which express in the same series (.N)

These will simply number with an additional upload number to allow local
respins, for example linux/5.15.0-30.31 -> linux-lowlatency/5.15.0-30.31.1.

Add support for BACKPORT_SUFFIX to be present and empty using `--` to
represent this situation (in a similar fashion to variants).

 SRU for jammy and kinetic. Already applied to unstable

 Currently unused, even if kteam-tools patch lands.

 This is support, for future new kernels.
