  [mlir][NVVM] Add managed attribute for global variables (#189751)

Add support for the `nvvm.managed` attribute on `llvm.mlir.global` ops.
When present, the LLVM IR translation emits `!nvvm.annotations` metadata
with `!"managed"` for the global variable, which the NVPTX backend uses
to generate `.attribute(.managed)` in PTX output.

This enables CUDA managed memory support for frontends that lower
through MLIR.
