Subject: [PATCH] Re-work OrtApi struct to satisfy C++20 compilers (#15183)

### Description
<!-- Describe your changes. -->
Remove `deletion` of copy functions from `OrtApi` as its initialization
no longer compiles in C++20.
Introduce a non-copyable member to implicitly delete copy ctor.

### Motivation and Context
<!-- - Why is this change required? What problem does it solve?
- If it fixes an open issue, please link to the issue here. -->
Inspired by https://github.com/microsoft/onnxruntime/pull/14901
