Cuda: ResolveDeviceSymbols now properly execute everywhere.

The previous version had two bugs that caused the JIT runtime errors.

1. It was building the executable without separable compilation enabled

2. All kernel launches will fail if any kernel is missing a symbol, that
   is why the call to file2_launch_kernel had to be removed
