[PATCH 02/12] CI: Remove useless/misleading randconfig jobs

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

Randconfig builds pick CONFIG_DEBUG with 50% probability.  Therefore
$foo{,-debug}-randconfig are two identical jobs with misleading names.

Furthermore, arm64 has a randconfig jobs for both the alpine and bookworm
build environments.  Both use GCC 12.2, so we have 4 identical jobs.  Delete 3
of them.

This leaves us with 4 primary randconfig jobs:

  gitlab-ci/build.yaml:381:debian-bookworm-gcc-arm32-randconfig:
  gitlab-ci/build.yaml:429:alpine-3.18-gcc-arm64-randconfig:
  gitlab-ci/build.yaml:495:archlinux-current-gcc-riscv64-randconfig:
  gitlab-ci/build.yaml:640:debian-bookworm-gcc-randconfig:

as PPC64 doesn't want randconfig right now, and buster-gcc-ibt is a special
job with a custom compiler.

Here is an example debug-randconfig with a release builds:
  https://gitlab.com/xen-project/people/andyhhp/xen/-/jobs/7312848876

If we want to run multiple identical randconfig jobs, that's spelt

  parallel: 5

in the configuration, and here is an example of what such a run looks like:
  https://gitlab.com/xen-project/people/andyhhp/xen/-/pipelines/1368824041

Notice the randconfig jobs have a 5 in place of a retry button, and show a
submenu when clicked on.
