### Area

CUDA Experimental (cudax)

### Is your feature request related to a problem? Please describe.

I've been wondering whether it would be a good idea to add a wrapper of `cuFile` to cudax.

### Describe the solution you'd like

Implement `` module with:
* `cudax::file` class wrapping operations with `CUfileHandle_t`
* `cudax::file_driver` object implementing `cuFileDriver*()` operations
* `cudax::file_buffer_registerer` RAII wrapper class for registering buffers in cuFile driver
* `cudax::file_stream_registerer` RAII wrapper class for registering stream in cuFile driver
* some more classes for batched IO

I've tried to implement it in #3360 without the batched IO. It is just a not tested proposal, may contain errors.

What do you guys think?
