[MLIR][Python] remove nb::typed to fix bazel build (#160183)

https://github.com/llvm/llvm-project/pull/157930 broke bazel build (see
https://github.com/llvm/llvm-project/pull/157930#issuecomment-3318681217)
because bazel is stricter on implicit conversions (some difference in
flags passed to clang). This PR fixes by moving/removing `nb::typed`.

EDIT: and also the overlay...
