Because clang-tidy is slow (and I'm not sure we can make it really fast), trying to run it slightly less. Also, I noticed we can shave a few minutes by disabling apt removal without losing too much free space. Note that since this removes the old clang-tidy, I'll need to change the branch protections before merging.
