llvm-11-dev provides LLVMConfig.cmake, which is required
for the build. In some situations, apt will install it
when installing llvm-11, as llvm-11-dev is recommended
by llvm-11. However, in some situations, it won't.
(It's unclear when one happens vs the other.)
So it's better to always recommend it anyways.
(cherry picked from commit 665f31b29c9bf333d40a133d7c4c25d95b056fe5)
Test plan
Manually investigated packages and files.
See discussion in #76
