Mark llvm::Any::TypeId as global in julia.expmap (#49124)

The dynamic linker needs to unify `llvm::Any::TypeId` across DSOs. In our case
`libjulia-codegen` and `libLLVM`.

See https://github.com/llvm/llvm-project/blob/2bc4c3e920ee078ef2879b00c40440e0867f0b9e/llvm/include/llvm/ADT/Any.h#L30

Fixes: #49121
(cherry picked from commit d8fa3c8)
