Dan Foreman-Mackey 618754d829 Move some common helper functions from lapack_kernels to ffi_helpers.
There were two helper functions for implementing FFI calls that were included directly alongside jaxlib's CPU kernels that will be useful for the GPU kernels as well. This moves those functions into ffi_helpers so that they are accessible from there too.
