  [NVPTX] Basic support for "grid_constant" (#96125)

- Adds a helper function for checking whether an argument is a
[grid_constant](https://docs.nvidia.com/cuda/nvvm-ir-spec/index.html#supported-properties).
- Adds support for cvta.param using changes from
https://github.com/llvm/llvm-project/pull/95289
- Supports escaped grid_constant pointers conservatively, by casting all
uses to the generic address space with cvta.param.
