Hello,

I believe recent changes (#48) have broken x86 compilation. The current bindings are currently setting a special case for x86 targets, replacing size_t by usize when generating the bindings:

This means that sys::OrtROCMProviderOptions expects a usize for the gpu_mem_limit field rather than a c_ulong. The current code does not compile with the following error message:

 gpu_mem_limit,
 ^^^^^^^^^^^^^^ expected usize, found u32

This PR handles the special x86 architecture case, and should hopefully maintain M1 mac compatibility from the previous PR.

This could also be fixed by casting into the expected type with:

let rocm_options = sys::OrtROCMProviderOptions {
        [...]
	gpu_mem_limit: gpu_mem_limit.try_into().unwrap(),
        [...]
};

Please let me know what your preferred solution would be, happy to amend the change request
