Improve host code bindings

[vosen]

Expected outcome:
Current host code APIs in zluda does not use generated bindings: every CUDA update requires manually reapplying the functions we expose. Instead zluda should use cuda_function_declarations macro, same as zluda_dump.
While at it, CUresult should be redefined to effectively be Result<(), NonZeroU32>

Comments:

• Probably should be done together with Update to CUDA 12.4 #286
