Extension to the callback API to support LTO callback routines.

Note
The cuFFT LTO EA preview, unlike the version of cuFFT shipped in the CUDA Toolkit, is not a full production binary. It is meant as a way for users to test LTO-enabled callback functions on both Linux and Windows, and provide us with feedback so that we can improve the experience before this feature makes into production as part of cuFFT. While we do our best to ship these binaries without issues, occasional bugs might be encountered.
Please direct any feedback you might have to Miguel Ferrer Avila <mferreravila@nvidia.com>, Lukasz Ligowski <lligowski@nvidia.com> or Arthy Sundaram <asundaram@nvidia.com>.
