[github] pre-cache llvm-project in Linux CI Docker images
Linux CI bots take a bit over 70 seconds to fully set their git repos
up, always starting from scratch. This can end up being a significant
percentage of their overall runtime, depending on the change they're
vetting.
Having a fresh llvm-project in the docker image can bring this down to
about 15 seconds; if the llvm-project checkout is 5 weeks old, the
number seems to be closer to 30-35 seconds.
In any case, that's a meaningful savings per CI bot run, so include a
pinned LLVM here.
