build-debian-based: 24.04+x86_64 - clang for 10.6 amd64-ubuntu-2404-clang18-asan

Github action where running out of space.

https://github.com/MariaDB/buildbot/actions/runs/20983884237/job/60314128205?pr=886

The requirement for clang in the 24.04 is only for x86_64 for the 10.6
asan build. This isn't required on other architectures and there's no
need for a 22.04 clang either.

In 10.11+ branches the msan builder is used for ASAN.
