As a first step towards the switch to 17/18 LLVM versions, the builds we do of llvm will switch to 17/18. This does not affect any running CI which only runs on 17.
Reason for change
Only supporting two version is our policy. It is time to start the switch to 17/18
Description of change
Change to build 17/18. Additionally changed running of the workflow to an overnight, rather than every merge.
