DynamicBuffer's AsArray() returns an invalidated array when there are no structural changes

Package: Entity Component System (ECS)

Won't Fix

1.0.X

The structural change is AddRange() itself. The compiler doesn't know that buffer1 does not alias buffer2.

Reproduction steps:

1. Open user attached “repro-project”
2. Enter Play mode
3. Observe Console

Expected result: No errors in the Console
Actual result: “ObjectDisposedException: Attempted to access BufferLookup<SomeBuffer> which has been invalidated by a structural change.” error message in the Console

Reproduced with: 1.0.0-pre.44 (2022.2.9f1, 2023.1.0b6, 2023.2.0a5), 1.0.0-pre.47 (2022.2.9f1)
Could not test with: 1.0.0-pre.44 (2020.3.45f1, 2021.3.19f1) (too many errors)

Reproducible on: macOS 13.2.1 (Intel), Windows 10 (by the reporter)

Note: Not reproduced in Player
