[clang] [llvm] Move MLIR before clang for in the list of external projects (PR #86085)

[Nathan Lanza via cfe-commits]

https://github.com/lanza created https://github.com/llvm/llvm-project/pull/86085

clang now depends on MLIR and thus we need to include it first for it's
dependencies to be added properly.
