[llvm-branch-commits] [CI] Test all projects when CI scripts change (PR #144034)

[Aiden Grossman via llvm-branch-commits]

https://github.com/boomanaiden154 created https://github.com/llvm/llvm-project/pull/144034

This patch resolves a fixme in the compute_projects script to actually
test all the projects we can when touching something in the .ci
directory. This ensures we test things like compiler-rt before landing
changes.
