[cuda toolkit v.12.3] Cuda Capturer causes "InvalidResourceHandle" due to "cudaEventDestroy" called on NULL

[Robin Söderholm]

Describe the bug
When using cudaCapturer, the events created during this stage is sometimes moved-from, causing the native handle to become null. This is then passed to "cudaEventDestroy", which triggers an "InvalidResourceHandle". A simple "if(event==nullptr)" in cudaEventDeleter.

To Reproduce
Steps to reproduce the behavior:

1. Create a c++ project.
2. Capture an arbitrary kernel.
3. Call "cudaGetLastError()": this returns "CudaInvalidResourceHandle" for me. Using "compute-sanitizer" does lead me to the cudaEventDestroy-call. Making the aforementioned quickfix solves the issue for me.

Desktop (please complete the following information):

• OS: Alma Linux 9
• Version 3.6
